Take your right arm and leave your rist on your upper right thigh and your fingers on the contact point. This should alert her. She will then make contact with your leg in the near future. If u happen to make contact first fine, but wait for the response. She will make contact with u.
Leg contact can induce arm contact, and vice versa.
If not contact tacts place in the movie, dont worry. All chivalry properties hold true. Her car- if she takes her car home, walk her to her car and then try for some contact. Your car- if you drive her home, open the door for her and assist in closing. Your top goal is for kiss, but remember u are not to expect this at all.
