Explain that for a lot of young girls, there’s a certain age or body type that makes it easy to put on weight. “If she said, ‘It’s a growth spurt,’ I would probably think it was quite healthy, and it wouldn’t bother me.” If you blame your age, you may be able to get him to understand that “she’ll put on weight even when eating the usual amount.” You’ll make an even better impression if you show a good attitude toward improvement by saying something like, “I’ll try doing some exercise.”
