How do you spot the difference between someone being nice (because they are a nice person) and someone being nice as an attempt to get close to you? ——— Being nice with a distance and being nice searching closeness differ in the attempted distance. When they come closer and you do alike you'll sense them increasing the distance when it's too close for them. There is however no fixed distance. People differ. It is always a bit of a risk to do that extra step forward that might clear things.
