a twitch bite

My sister is in town and we were all outside swimming. For some reason there have been a lot of bee's in our backyard. I hate bugs, so I run when I see something like a bee. I was enjoying my time in the sun laying on my chair when a bee started flying around me. It just wouldn't be right if I didn't wave my arms and make noises or scream over something so little.

Tanner says "Mom, whats wrong? What are you scared of?" "Oh nothing Tanner, don't worry about it, I just have a twitch." I was trying to be brave in front of Tanner. Chad says I have turned them into babies when it comes to bugs.
A little while later the bee moves over to my sister and she does the same thing. She is more of a freak than I am when it comes to bugs. So now she says she has atwitch so we don't freak out Tanner.

Tanner is swimming peacefully in the water and all of sudden pops out of the water and says "Mom, what is a twitch bite?" Man, he figured us out anyways!
