Hi,this is my 1st post on this forum.I have one strange situation with one girl who work as cashier on market in building where I live.This girl always provokes me when there is no much people inside that market.And she do that in funny way,I also respond on that.Even when I passing by that store,she go outside and tell me something,we joking.I realize that I must do somthing because I also like this girl,she is beautiful (there are 10 womens in that market and she is most beutiful there).
One day I decided to ask her for coffee,I ask her after some chatting: Well,*** I would like to drink coffe with you.
She: (suddenly put smile on her face and her eyes blinking,that smile is constant through all conversation): I dont know
Me: You dont know? Who we can ask if you dont know?
She: shrugs and say: Dont know
Me: Ok,give me your phone number and we will arrange that coffee
She: Nooo,cant give you my number
Then,I said OK,and pay and leave and say bye bye like we always do.After that I spoke to her normally for some 20 days like nothing happened.Then I decide to try one more time to ask her for coffee.I buy some strawberries and go to her to pay bill,and we chatting and I ask her again: So,when we will drink this coffee?
SHe: (her face is red now and just smiling)...
I wait some 5 seconds and ask her: do you come to realize?

(because last time when I ask her was 20 days ago)
She: I dont,and smile to me
Then I just walk to the exit door and she said: When you eat strawberries,and smile.
Me: when I eat them?? It will be fast.....and I leave that market
Now,I dont know is there some possibility that this girl joking me around or she is just shy???? She give me constantly IOI and then when I ask her out,she respond me I DONT KNOW
Any advice??? Thanks people
