Hello. I got pretty good IOI from a girl, although in a work environment (probably bad idea but fuck it). After really nice conversation I asked her would she like to go out and continue the conversation further during a break (we work at school) to which she replied "I'll think about it" although there is almost no chance we will see each other before the break.

Is it a shit test? Does she try to save the in work relationship without saying "no"?

Any ideas how to proceed? To be fair I usually had definitive yes or no this is a first time I got this reply, and was wondering what is your take on it?
