When I was in high school, kids did not use umbrellas when it was raining. Which is the STUPIDEST thing ever. I mean, it's #raining--use an umbrella! But we didn't. I don't know why. Because it's kind of a "nerd" thing to do? So we just stood under a tree at the bus stop.
When I went to college (University of Maryland--go Terps!), EVERYBODY used an #umbrella. Because we're adults and we do adult things, right? I was so happy to see everybody on campus with an umbrella when it rained.
