The thing is, I don't usually forget. I'm just waiting for it to happen. But sometimes, my mother will keep it hidden past like 3 to 4 gift-giving occasions. And I'm stuck with the dilemma of wanting to remind her and not wanting to because she'll keep it tucked away for even longer.
Right now there is a DVD of Fantastic Mr. Fox (which I've never seen but it is one of my favourite Roald Dahl books so I really want to see it.) somewhere in my house and it has been there for at least a year and I'm dying.
