?ladies im 28 shes 32, is there a chance in it?

ok there is this woman I like that works at the store i go to each day b4 work. a few months ago I would see her every day and we would small talk, like good morning, how are you, how was ur weekend etc. she told me it was good she went out with her friends. then one morning when i yawned she was like why soo tired, its early, i said i must be gettin old, she was like aww no your not, then i ask her how old she was, she said me her age. that was the last time we talked, til last week, when my shifted changed and her shifted changed when i came into the store, and saw her i was shocked and she had a huge smile and said hey. we talked briefly she asked me how I was and what I do, I asked her the same and she told me where she worked. Then today when I was gettin coffee, she came from the counter to where I was and talked to me she said I havent seen ya in a few days, I was like oh, then I asked her how was her weekend. I asked her if she had facebook, she wrote down her name, and I breifly looked, and I saw her pic with one of her friend. Ladies, if you were at work would and a guy is interested in you and u had a bf or with someone, would u engaged in a conversation with another guy or give ur name for him to find you on facebook?, when he askes how old u were, what you do? do u think shes single? how can i find out with out being blunt. what can i say or ask her? do u think she may like me somewhat? whats the next move? thanks kerry
