Be open to the other. You actually always know what each other means by a certain gesture / word / behavior, but you don’t always tell each other. You better be open about it, then you both immediately know where you stand. Furthermore, it might be good for some to choose at least 1 person in your area who will tell you more about the contact. Sometimes you help to put things into perspective, to place them or to get them clear. at least in my case.
