I love Sheldon*. I like to have 'my spot', and I think gift-giving opens up a whole can of worms. Quite often, I just don't get the joke. But, note to self, it's only funny when Sheldon corrects his friends because it is not real life, and his friends only forgive him because it's in the script, and otherwise all the actors would be out of a job. I am not Sheldon, which is probably why I've felt a bit like this all week.
* The GG introduced me to The Big Bang Theory, and it's brilliant - but not to be used as a guide to how to behave in company, of course.
