Hi.<br /><br />
Simply because they were never taught about health at school and in their homes.
I don't spit...it's a vile habit.
Don't think about it! Just step on my DNA!!
They are practicing in case the perol catches fire.
I wish they would stop that too. It looks nasty.
don't step in it then....
Most of them smoke and therefore the spit and some just has the need to spit...
