I lost weight in the summer vacation and lost more than ten kilograms. My chubby face is gone. Why don't my friends think I've changed a lot for a long time, but my friends around me say I don't feel anything? It is normal. People around you gradually get used to a person's changes, but friends who haven't seen each other for a while may feel that they have changed a lot, which is compared with the last time they saw you and this time. Think about it. Your two primary school classmates, one meets every day and the other doesn't meet for two or three years. Then you must think she hasn't changed much, because you are used to every little change. If you don't meet for two or three years, your impression of her will remain two or three years ago. At this time, you will feel that she has changed a lot. She should be taller, more beautiful, and her voice is better and healthier.
