Yes, I guess so.
I mean, these guys aren't being barbaric och uncivilised or anything like that, they just have a much more of a tough attitude around each other, such as talking with fairly strong voices and all playfully shoving each other and giving each other friendly hits on the back and things like that, and they seem to immediately stop all that behaviour if I interact with them.
I guess it is mostly a matter of them realising that I am much smaller and much more vulnerable than them, and that they need to be careful;
sort of like how people become more careful and sweet-spoken among children.
