So I walked into the kitchen the other day to find my son blindly reaching his hand onto the counter. I say blindly because my son is not yet tall enough to see on top of the counter. First he pulled down a small toy I had stepped on the night before, examined it and the pushed it aside. He then proceeded to stick his hand back up, and try for something else.
Next he pulled down my keys. He took his time to exam each key (there are ten on my ring), before he said "No", and also pushed them aside. It was at this point that my curiosity got the better of me and I asked my son "What are you doing?". To which the two year old replied "Nothing", and stuck his hand back up on the counter to feel around.
The next thing to come down was my wife's keys, and he once again examined each key. He carefully looked over every key until he came to her car key (the longest one) said "A-HA", and ran away holding the key.
At his point I had to see what was going on, so I followed. And as I turned the corner, I was just in time to see my son use that key to pop the lock on our bathroom door, and barge in my wife on the toilet.
I laughed so hard, I think I peed.
