Lethargy?

Just got my first "random" reference call...a lady asking for the definition of lethargic. Nothing too hilarious, but it was a first for me. It's interesting when people ask you questions because they're certain you know the answers off the top of your head (I did know, of course).

I, by the way, am feeling quite lethargic myself at the moment. I want to go home and start Christmas break already.
