I've been with my boyfriend for two and a half years and it seems like at least once a week I learn something new that surprises me. Last night I found out he didn't know what happens when you put Mentos in a two liter bottle of diet Pepsi. It surprised me because it just seems like such basic knowledge, especially since I learned about it in a middle school classroom.
There are some bigger things I've learned about him as well but I won't go into for the sake of keeping his privacy. Some are weird, some aren't really good things, but plenty of them just make me love him even more.
