As I was walking today an elderly man I was passing told me in an annoyed-sounding tone to eat more and put some weight on. I responded with "I wish I could." because my high metabolism makes it difficult for me to gain weight, so I'm always a bit underweight. I didn't explain that, though, as I was put off by his tone. He responded with a rather irritated-sounding "You can." I wouldn't have been bothered as much had he said it in a light-hearted way, but he sounded so hostile it made me feel a bit angry and upset. Would this bother any of you as well?
