Do all boys play “rough”?

This seems to become a recurring thing with my almost 4yo for the last few months. I hope not but here goes -

He makes a good friend in daycare and then a few months later, he complains they pushed him. The first time it happened was when he wasn’t very verbal and didn’t clearly talk about it. So I thought it was just an accident until my LO came home with bruises (scratches). We changed daycare when we realised the lack of attention or concern from staff (after I complained a few times) and few other reasons.

Anyway now he made another friend. Last week, my kid told me this guy is the bad guy. After I asked him why, he said this friend pushed him. I talked to new daycare staff and they saw this happen the same day and talked to both the kids. I don’t think it happened again.

Now my kid has another friend. My kid says this one is funny and naughty. We did a play date today with this kid and a girl from the same class (1st time with both). i noticed this kid run around indoors more than my son and the girl. This kid at 2-3 instances grabs things that the others are playing with, put his face very close to my son’s and stand in a “macho” type of position, even sort of push my kid to a side while running.

By the end of the night, all kids are tired. Mine started crying. I am not sure if he was just tired. But he gets in the car and says this kid pushed him.

I obviously don’t like it. But I grew up going to girls schools and didn’t have brothers. My cousins are way older than me. So I don’t know if this is typical for boys.

I want to be sensitive to my kid’s feelings. But I am worried if he is going to become a lonely kid because a lot of the boys seem to be playing “rough”.

I also don’t know what the etiquette is when I see these things happen. Usually I try to tell my kid to just give the thing they are grabbing to maintain the peace. But this isn’t fair to my kid and will lead to bigger issues in the future.

I also don’t know how to correct others kids when they are misbehaving with mine.

Should I just not do play dates with such kids?
