Would it be ok to ask a girl out i know from badminton?

well i think next practice that you go to you should talk to her and be really flirty and see how she responds, and if you feel confident enough you can ask her to hang out with you. you know it doesn't have to be like anything to special since it is a first date and you don't know her that well. you know.you don't want to put too much pressure on her. but if you think that she's not really into it yet then just keep on talking to her over the next few weeks and show her that you're interested and then tell her how you feel and see what she has to say. if she likes you then ask her out. good luck!!
