I was at the gym one time. I usually just keep to myself and never talk or interact with anyone. In return no one talks to me which I'm okay with.

One time I was on a stair climber machine beside one lady. I finish and get one and the lady on the machine beside grabs my attention and says "hey" as she takes out her earphones.

She smiles and says "I've noticed you around. You look like you've lost a lot of weight. You should be really proud of yourself". I actually felt really uncomfortable with it and just said thanks back.

In the days after I just never used that machine again and walk back and forward in the long way around the gym to avoid her.

Another day she happens to run into me again in another weights machines area of the gym. She gets on the machine beside me and awkwardly says "eh....Hi". I just said hi back without making eye contact or talking further.

AITAH For avoiding her?
