I envy people who can do that.
Very hard to find someone I can connect with. The last really intense (brief) relationship was early spring of last year, and I still can't stop thinking about her.
Helps that I moved away. Doesn't help that I don't use booze or drugs. But then again, if I drank, it might have lasted longer (I don't, and that was one of the problems for her).
Some eternal sunshine would be most welcome, but the price of a spotless mind is too high for me.
