I have two stories, one was handled well by the parent, the other...
One was not actually at Christmas time, but at Greg's 7th birthday. I remember him opening one present and it was obvious that he was less than thrilled with it. He didn't throw a tantrum or say anything, he just went really quiet and didn't say anything. His mother Ally immediately swooped down, took him aside and when she had finished speaking to him, he went and made a very gracious, if a little belated thank you to the giver.
The other was at last Christmas. Keira has a five year old daughter, Kim, who is obsessed with Angelina Ballerina. Aunt Lily thought that because of this, Kim might like to see more ballet, and bought her a DVD of a Nutcracker performance. Good gift, you would think. Not so Kim. When she opened it she exclaimed loudly: "This looks BORING!" Keira said absolutely nothing. Lily, taken quite aback, explained to Kim her reasoning behind the present. Kim promptly told her: "You should've gotten me Angelina stuff then". Keira chuckled a little at this
. Kim will not be getting anything from Lily this year, so it will be interesting to see how things play out on Christmas day.
