If its out of da blue, I would have a nice laugh on top of evrything else.
I suggest u jokingly tell da guy b4 making more advancements.
When i was young, they were a few fellas who have good feelings bout me but as a young kid n not prepared 2 have any kinda relationship, i turned them down. Now as a young adult, there r still gals who approach me but in my opninion, gals who approach u directly asking for hp no. or wateva, these r da reject ones who r desperate for a bf. Try being a friend 1st instead, 1 step at a time plz. = )
