You can’t say that, “retarded”. That is horribly insensitive and politically incorrect or some such garbage.
There are some kids I’ve seen that if were mine I’d have left em at the grand canyon too.
“Retarded” used in a derogatory manner is absolutely rude, but the word itself refers to a lack of development in some area. In the purest sense of the word, retarded is actually the proper term.
Of course, I’m not given to being politically correct. A handicap doesn’t make you “handi-capable”. It’s just what it sounds like... that being said, handicapped people accomplish incredible things, sometimes more than perfectly able people because of their drive and determination.
Words mean things. Sometimes our associations with those words make them to be something they are not. But there is always a more correct word for a given situation than another... political correctness aside.
