The last time you hit someone, how old was he or she?

I can't remember when I purposefully hit someone.

Accidentally?  I hit a friend last week, as I was waiving my arms while telling a story.

However, I daily wish I could "Gibbs Slap" a few people.  LOL

Does accidently count?

She was around 40.  I was a long time ago when I first went to work.  I was just learning how to throw a load so I was concentrating hard in order to do it right (perfectionist).  I was crouched down trying to put up I think dish brushes or the like, when the Floral department lady came up behind me and touched me (I didn't see or hear her ).  Scared me to death.  My fight or flight response kicked in,and I quickly tried to stand up with my arms and fists trying to cover my head.  In doing so, I decked her.  She ended up across and several feet down the aisle on her butt.

9. 

19 or 20. I was KOd in the third round.

About age 40, the janitor in the building where my friend lives and where I lived before relocating. I landed him a slight punch in the shoulder to emphasize me telling him "stop.being such an idiot!"

I slapped an 11-year-old boy when I was 13.  I guess he was 11, I’m not really sure.  I was at a music festival with my friends and he kept video-bombing me when I was making a video of my friends.  I slapped him on the third time he jumped in front of my camera and screamed.  He didn’t to it again.

I also got into a big fight with the mean girl when I was in high school.  I think that was in 11th grade.  I punched, kicked and pulled hair.  One of the boys pulled out his camera and yelled “Chick fight!  This is going on YouTube!”.  I grabbed his camera, stomped on it and told him it wasn’t going on YouTube.  That was the only time I’ve been in a physical fight.  I’m normally pretty non-violent.
