If you want know why "happy" people stand in the rain its because: They love
walking in
the rain
because no
one call tell
that they are
Crying

Now think about that if you see someone walking in the rain and they have nothing to do and they are usually "happy" all they are doing when you are around them is faking a smile to make sure you don't feel bad for them, they try to make sure you don't cut yourself or get depressed but most of the time they do it to themselves and don't take their own advice for themselves.
