Define WALKING?

Josh is very close to walking.  He took his first step up at the cabin on Friday and then three steps on Saturday at Tony's parents house (during the BYU game - GO COUGS).  Since then he has been taken a couple steps at a time here or there, until last night when he took about 10 little steps from me to Tony.  THEN this morning he did about 6 steps...so is that walking?  I don't really think so.  I think walking is when one can walk from one end of the room to the other, but it is pretty darn close.  Tony said a little while ago that he thought Josh would be walking by his birthday and I said that I didn't think he would, so now it is like a little bet we have going.  But we didn't really define "walking" so I guess we will see who wins.  His birthday is on Tuesday...I think that I might lose!
