@CookieLover_1031 see how they act around you? If they stare at you and if they might purposely try touch you in subtle ways, like elbows bumping together stuff.And if they avoid eye contact and stuff with you or stare at you in the eyes a lot, check if they have a faint blush or if their acting nervous our trying to act cool and stuff to impress you, maybe flirt with them a tiny bit to see their reaction.Hope that helped :D
