Who did it ?? - The case of the mysterious boo boo

Yesterday I was giving Sean a bath and like always I let him play in the water for a few minutes before the actual 'bath' itself. After several minutes he still didn't seem ready so I had to finally tell him, Sean, Mamma has a boo boo in my hand. So lets take a quick bath.

And that started it all. The next few minutes were interesting to say the least.

Sean: You got a boo boo?
Me: Yeah Sean, see in my hand (it was my tendinitis flaring up again in my right hand and it was painful)
Sean : How did it happen?
Me: I dont know sean (usually i know but this time i couldn't remember what triggered the flare up)

At this point he really thought that some one hurt me and thats how I got the boo boo. So he said,

Sean: Who did it?
Me: I dont know Sean.
Sean: Appacha did it?
Me: No Sean, Appacha didnt do it.
Sean: Ammachi did it?
Me: No Seany
Sean: Baby did it?
Me: No
Sean: Sean did it?
Me: No
Sean: Daddy did it?
Me: No...
Sean: Jogging did it?

At this point he had a look of concern on his face as he was trying to narrow down the problem and I just had to give him a big hug and kiss his forehead and assure him that everything is fine. He seemed so determined to get to the bottom of this. I dont think in his mind he thinks that Appacha, Ammachi, baby, he or dada would hurt me but i guess those are the people he's close to and come to his mind first..

Hmm...I'm beginning to think that I have a budding Sherlock Holmes at hand...
