You're too skinny. You talk too much. Was your hair always that thin? He'll leave you if you don't change. Yes, others can make comments to your face or behind your back. It has happened to me and it has happened to all of us. What matters most is how we deal with it. Letting others determine your self worth lets them win. Ignore that foolish stuff and make your own life a good one by doing your part and not being an adult bully yourself.
