I hate people who get overly excited.
Why do you think they get overly excited?
Because they see something irresistible and get too emotional.
It seems like they're just happy. It's fine for them to be allowed to react however they want.
People in public should stay calm. I hate seeing children and teens acting that way.
Do you ever think that other people might not like the way you do things? It's good to just let people be themselves.
