umm the way you said it..... 
this shows no clue that you do not have the use of your legs...RTHolmes does not need to apoligize 
I was pretty much thinking the same thing.  
Although most folks probably wouldn't let you know they don't have the use of their legs if they were trying to keep a joke going or make a funny on the BBS...but then a smartass comment about someone possibly being overweight shows up and they might feel compelled to admit it to break about 12 inches of truth in someone's smarty-pants.  Ya never know..
