Fat experiences

If so, how did they react?

While not a gainer myself, I have heard mixed reactions.
When fattening my now husband, he didn't exactly say he wanted to get fat, but they tried to get him to exercise, which of course he was reluctant to do as he got fatter. There were some disagreements about his gain, but eventually he did tell his sister that he was happy where he was, and although she has a hard time dealing with it, she eventually stopped trying to promote exercise.

I have and received displeasure. Now live on my own and happy being me.

You’re a moment in time, make it a great one and one of happiness of being who you are.

I did make this mistake at one time in my life. I was young, and was starting to gain some weight. My parents noticed it and made comments and I said "Yeah I know I'm gaining, I want to be huge" I was forced to run on a treadmill since my grandmother was worried about my weight, now I know better not to let my family that I want to get huge. I'm sure they will make comments as I continue to gain weight, but I'll just brush them off. I don't see my family that often anyways.
