Laugh all you want, it happens.
Don't take it personal. I just find it amusing

I suppose the only scenario under which I could see any actual "damage" occurring, was if a prong got caught in a bed sheet. I have been wearing my rings to bed (necklaces, watches, and earrings too) for my entire adult life (I just turned 40 this year) and I have never had a ring snag. In general, sheets are pretty soft & smooth, much like the prongs on my ring are smooth (and rounded). I just don't see it happening, which is not to say that it can't happen, but I'm not the least bit concerned.
