Wasn't me

My mates little boy is 2 years old.
He went into the kitchen one afternoon and we heard him moving a chair and being very quiet so we went to see what he was doing. He was standing at the sink pouring a whole bottle of fabric conditioner down the drain. Then he turned around and put the bottle down. My friend picked it up and asked him why it wasn't full.
"Daddy did it!" came the reply and he pointed out the kitchen window.
His dad doesnt live there and he hadn't been round for 4 days...
