Just contemplating the idea that three snugglers I spent several hours of snuggling with had said they would keep in touch eventually didn't. The very first one was after months of snuggling. They just disappear. Delete their accounts and probably change their number.
So I think it is wise to treat each session like it may well be the last time you see or hear from them again. That will at least make it less of a downer when it happens.
I'm overly sentimental though. So it's probably odd to care.
