Old acquaintance didn’t recognize me after weight loss, treated me far better

Using IF I’ve lost about 100 pounds in the last 18 months and my face especially just looks so different now. Ran into a friend of a friend who I had met maybe twice a few years ago. When I was heavy, they barely acknowledged me. Today, without realizing they had met me before, they were SO nice. Like a completely different interaction than the times before. Sometimes I wonder if I am just paranoid but it does seem like people have been treating me far better than when I was heavier. This one stood out though.
