My mom works with challenged children as well! I personally don't see the problem with the term, but if someone does, who cares? It's not an offensive term, it's a loose term.A term with a negative connotaion, not always a negative meaning. The person who hears it determines whether or not it is offensive to them. I can take almost any word anyone says and take it personally or offensively, but I don't. If I did, my life would be one big constant correction. I choose not to live that way. If others do, that's fine, but dont expect me to hold my tongue because you turn an innocent word into a negative comment!
