Impress him/her.

Show off your hidden talent to him/her anytime in a middle of the conversation when the timing feels right. Don,t look all ignorant and great when doing so. This is definitely conversation material

For example: If you can sing or dance, do it, show them what you can do, let them be wow,ed and she/he,ll probably ask you, ,where,d you learn to do that, and move from there on :)
