No it won't be weird..ask her out. I kinda like this guy at my work and I think he likes me but I've brushed him off and so he's probably lost interest if he did like me. Anyway, I WISH he would ask me out. Every girl is flattered by being asked out...even if there aren't interested. What do you have to lose? Ask her out for coffee, a drink, or dinner, or just to hang out. Good luck! Don't be scared..you only live once and you miss every shot you don't take. Don't let this be one of those shots you wish you had taken.
