Why is it odd for someone to cry over something? Arent you guys humans?
It is a natural behaviour, we cry about things we love and hate and things that are happening like somebody in your family dies or an accident happens where a lot of people die...
You have tears of sadness and tears of joy.
Anybody mocking/laughing at that guy is either a kid or is inmature and you probably have been in a similar situation when you cried about something so stop fooling yourself, just grow up or stay kiddie forever.
