Based on the context and the answer, generate a question. 

Context: You 're supposed to hand stuff down to your younger siblings , not the other way around . That 's how it worked for us for a while , until I turned into the preteen chunk that I was and anything I would have discarded would have been too large for her . But then all of a sudden it started going in the opposite direction . I lost weight and she lost weight , and suddenly that meant that she was passing stuff off to me until she got way too skinny for me to catch up .

Answer:

We both lost weight so her clothing fit me better .



Why did my sibling pass clothing items to me ?
