Hi!
Glad to hear from you again. I haven't seen you as much on the boards....
Anyways, why did you start? That is a loaded question.... My answer would be something like Just because I wanted to or I liked how it made me feel. Simple as that. It really does not matter what is said to normies.... we look like idiots no matter what! No explanation will give them the reasoning that they are looking for. Our reasoning just does not match theirs! Its like cats and dogs, they are just different.
No good answers to give you here I guess. Just knowing that they will never totally understand may help you avoid fighting the issue with people though.....
Luck!
