The real question isn’t “What can I buy for him/her?”.
The question we should ask ourself with rather be “What can I do for him/her?”
A simple gesture often worth so much more than something bought that will end up in a garbage. A good memory, something personal, won’t be forgotten.
So when you’re asked what YOU want for Christimas, show people the way asking for a simple service instead of a material & costy thing.
To conclude I ask you : What do yu want for Christmas ?
