Oh, it's so nice to hear that I'm not the only crazy one! In fact, it sounds as though none of us are crazy - we just have strong preferences.
I love my bone china mugs, and have several 'favourites' depending on the mood I'm in.
I also have the 'posh' china - a precious set left by my dear late mum, who was always very particular about having the table set properly. That comes out on very special occasions only, although I sometimes have tea in one of the beautiful cups just for a treat.
Teapots are my obsession - I have twenty-six, and I use them all (not all at once!)
