Me: I know! And I bought this sweater because it was actually long enough...once.
Beth: I know how to fix it. I do this all the time with my clothes. Here, I'll show you how.
It's sad that she knows these things already. If the growth spurt that has now lasted approximately 8 years continues, she will have many more years of pulling and stretching clothes that don't quite fit.
But I'm thankful for the help. Tonight my sweater fit me again for a few minutes and I had fond memories of my first few wearings of it.
