I had a similar problem at one point. I was working at a grocery store deli and decided to go on a diet to get rid of the 10 or so lbs I gained in college.  You would’ve thought I told them I hadn’t eaten in a week or something. They were like “omg you’re so skinny already you’ll be underweight what is wrong with you.” To which I had to REPEATEDLY respond. “No this is fat for me. I am 130lbs, yes 130lbs, I can get down to the low 120s without being considered underweight” Also everyone thought I was already like 100lbs?! Like listen sweaty I am 5ft 8in there is no way on earth for me to be 100lbs and still have the muscle mass to pick up 75lb boxes of chicken. Also it was considered a big fucking deal that I was able to do this? Like no one thought I’d be able to. In their minds being a normal size means you’re about as strong as a dry piece of grass.
