"I'll do it myself"

Aidan has been obsessed with getting a Thundercats toy sword for a few days now - he woke up during the night and asked me if I had got him one yet, and it was the first thing he asked about this morning when he got up. He asked again after nursery, so I told him that the shops didn't have any, and that we'd have to buy one off the internet. 5 minutes later, he asked again if I had ordered it - when I said that I hadn't yet, he said "och, I'll do it myself!" and stormed off to the living room. When I went though, I found him with my laptop out, trying to order one off the internet!
