That's pretty sad, really. My son has really loved some of the bugs but when it has been a little while bugs have to go back in a cache. I don't care if he had a tantrum. I would just put him in his room until he was done with the tantrum. Oh well, I guess not everyone deals with kids in the same way. Letting them keep a TB would be like looking the other way if they stuck a candybar in their pocket at the store IMHO.
I agree I wouldn't let my kids do that either.
