For example, the friendship between girls is gentle. There are often some intimate movements between them, and they often hold hands. I will tell my best friend something about my heart.
As for boys, according to my observation, their friendly way is somewhat special. They will often fight together, often close, but after the fight, they will still meet and play basketball with a smirk.
In short, I think: the friendship between girls is subtle.
The friendship between boys is bumpy.
PS: Of course there is a difference. After all, people are different! ~~
