Can I have some smalltalk with the girls without getting stuck?
Sure you can, as long as you don’t sit right on her lap. Seriously, if you sit next to a girl and try to do some conversation, it’s fine. As soon as the girl starts touching you or vice versa, you signed the contract. If you don’t want to go to the room with the girl don’t touch her, point out that you just wanted to be nice and have a conversation when she starts touching you. Sun leave a little distance between the girl and you and don’t overdo it regarding time for smalltalk.
