I thing this isn’t a “first date” thing to say, but I also think that it all depends on a person you’re dating. If they suck- they suck, regardless of the number of dates you’re on with them.
Last time I was seeing someone, he knew I was into fitness, but I waited to tell him what is it that I actually do.
I eventually told him on the fourth date, and boy was I wrong.
The minute I told him I literally felt his perception of me changed and he changed his attitude towards me. It’s like he started to define me (and by that I am not thinking in a positive way) only through that, despite all of my other characteristics. So, I guess I am sorry for not telling him immediately, it would save me the trouble of seeing him next three times. 🙂
