A dating post? Why not. It's April, it's going to be shitting out, here are some bad weather date ideas.
Build a snow man!
Yes, I know, April, no snow, but I couldn't resist this one. I mean, come on, who doesn't like acting like a kid from time to time? People who are no fun. That's who. So, instead of getting angry at the snow and life and wondering why oh why did your ancestors settle HERE in this God forsaken land, make it your friend and build a snow man! Bonus points if: the carrot gets mis-placed. You do it sneakily in the dead or night on someone's front yard. I mean, who'd be pissed to wake up to see a happy snow man in their yard? Well, if you put the carrot in the wrong place they might be...
Build a blanket fort
I refuse to pretend fun things are fun just because I'm an adult now. If anything, they're more fun now. Line it with anything soft you can get your hands on (pillows, blankets, sleepings bags, that foamy thing on your bed). Drag in snacks, and a laptop (if you have one) with movies from your childhood, and a bottle of wine. There are some other "adult" things to do in there, too.
The internet tells me that competition makes people horny. No, really. The internet would never lie to me, so, bust out the video games (assuming you both play them) or board games. You can also play cards, arm wrestle, staring contest, thumb war, or both try to come up with a more awesome story (Pro tip: Everything is better with dinosaurs and robots. EVERYTHING!)
Sure, you can go for a nice long walk in the park and have sandwiches, or wander through the nature trails and find a nice cozy spot. Or you can do it in your blanket fort.
The Boy is not artistic, as he will quickly tell you if you for some reason feel the need to as him, but that doesn't mean I don't fully intend to inflict this upon him. And soon. The internet suggests making collages (one article went as far as to suggest making an R-rated one, which kind of horrifies me) but that's lame. Dig out the pipe cleaners and make animals (or dongs). Bust out the macaroni and glitter and make cards for upcoming birthdays and anniversaries (or dongs). Grab a balloon, some news paper, and some glue and make paper-mache hats (or dongs). Have tooth picks and mini-marshmallows or gummy candy? Make tiny buildings and make a tiny city. Then dig out an old toy (I refuse to believe you do not have some form of toy left) and have it rampage through your tiny city. Then eat the results (or make dongs). If you have a surplus of boxes you can make a city out of those and go Godzilla on it's ass.
Think back to what you were forced to do in school (or by my Mother. You may think you've never done arts and crafts with my Mom, but trust me, no matter who you are or where you are, you have) and see what you gave kicking around.
Rubber boots are your friends
Drop $20 on the silliest pair of rubber boots you can find (or normal ones if you're boring) grab your umbrella and go stomping through puddles. People passing by will be jealous of you.
Digital Camera are also your friend
No, I am not suggesting sexy time pictures, although, hey, if that's what floats your boat. What I am suggesting is just fart around with the camera. You can take pictures of each other, of the poopy weather, or, if you're childish silly like I am, I have another suggestion for you. Those toys that were rampaging through a tiny marshmallow and tooth pick city and write up a quick and silly adventure for them. Then take pictures to tell that story. You can add text and end up with your own story book, which getting printed nicely would make for a great gift for said significant other. You can be extra cute-sy and make the toys you're sending on the adventure the two of you.
Rubber Ducky, you're the one, you make bath time lots of fun!
Rubber ducky optional. Candles, music, and bubbles? Also optional, but just taking a straight up bath together, kinda boring.
You can be romantic and grab wine and put on some smooth jazz, or you can pound back some shots, blare the music, flick the light switch and pretend you're in a night club. Sure, you'll feel silly but, hey, no cover fee to get your groove on in the living room, and no one is going to judge you for busting out your less savory moves (some people are not fans of the sprinkler, apparently)!
Okay, maybe these are less "date" ideas and more things to do to amuse yourself in the rain, but, hey, good luck finding THESE on a dating website. Take THAT 98% of all dating websites ever!
