OK, another mom commentary.

My children usually stopped complaining when they saw the good deal they had.
As far as the shaking goes, my theory is Elder Twede was bitten by a wolf spider and was going to phase into a werewolf but kept his cool and didn't phase. Way to go Elder Twede. You kept your human form. If you don't understand this post don't worry. Come up with your own theory.
