I mostly hang out with boys, not because I'm "that girl" but that's just how it has happened. So when i hang out with them I sometimes go w/o makeup, but it's not like they care. I ussually at least try and throw on some eyeliner and mascara, cause I think I look tired w/o it. If I'm not wearing makeup I'm ussually wearing a headband, a hoodie, and jeans or something, so at least everything goes together, lol.
But yeah, guys don't always think before they speak, so sometimes I get "you look wierd today" Or "whats wrong with you" as soon as I walk through the door.
I ussually carry my "basic face" makeup with me in my purse just in case.
