This is so funny!  Why is that when someone falls we laugh...or at least I do!!  This isn't a 'falling down the stairs story' but I remember a time, at work, when my best friend was running late and she had her bag in one hand and her Sonic drink in the other and next thing I know, she's down.  She is one that would put her life on the line to save her diet coke and boy she made sure not to drop that sucker lol.  I didn't ask (right away) if she was ok because I was laughing so hard. I literally couldn't breath from laughing so hard.  Sounds terrible, but it's so much funnier when your best friend takes a tumble than when a complete stranger does.  She laughed, too, but after a while she was a little annoyed with my laughing and it eventually got 'old'....  I just love her so much...good times, good times.
