Ever have a question about something that you would like to have answered, but you will never find it on google??
Mine is:
How do blind people know when they are done wiping??
Hope they wash their hands well, or at least are not nail biters :p
Well most blind people have guide dogs.. Suppose they have formed some system for ass wiping.. If there is nothing there, the dog doesn't bark, if there is, the dog barks... Keep wiping till the dog doesn't bark! :p
