text: how do i know she is single or interested? she works at a drug store by my house and i do not want to make it akward in the future. i am 24 and she seems to be about the same age. how do you know she is single and interested? well the answer is: you don't!! and you won't unless you ask or somehow figure out a way to get to know her better..i.e. by sparking up a conversation and taking it from there! so far you've got really vague assumptions of her age for example..so the only way to find out real hard facts is to make a move and spark up casual conversation and if she responds positively you're on the right track! good luck!
