yes its possible also if he is an empath he definitely will empaths will tend to get emotional with a great many things so girls if you ever find a guy that cant stand to see those animal rescue shelter commercials that show injured animals or watch the funeral of a soldier he doesent even know and cry or shed tears at movies or tv episodes that have babies being born dont laugh at him he might just be an empath
I would be worried if he didn't.
Yes. Crying is a human emotion.
