Ok, I am not in the state of naming cars, computers, cofffee maschines etc. I only give pets a name.
No, I don't feel guilty towards my decks. The ones in the book case and the boxes are the collection and they usually stay collection (I admit I usually do not part with them, prefer ordering new ones for trades, because parting with something out of the collection box seems unfaithful to the deck to me - call that insane).
The everyday reading decks go with me in the rucksack everywhere - to work, to cinema, to fairs, to friends...they are a kind of natural extension of my hands and as I only have 2 hands it would be difficult to have all other decks with me.
