Couple months ago my mom touched my cards, because I did a Tarot reading for her, and I haven't cleansed my cards.
When I was reading for myself, I asked A LOT of questions. Does that mean ALL answers were wrong and I should ask same questions again?
Well, I read for a lot of total strangers, and I never cleanse my decks, and all the readings are worthwhile.
Why do you think your relationship with your deck is so fragile that one person touching it months ago could affect it more than your touching it all the time? That sounds like deep-seated insecurity on your part, to me.
