Brilliant Irony of "Weighting"

It's not really about couple, but about time. Look closer: outside, she has a big watch under her arm, which means that time matters a lot for her: no time for birthday (the cake), no time for family (she takes one photo, the other ones fall and break), no time for herself or her couple (the tea), she ONLY wants to run, run fast. She prepares her old age with the walking stick. But she lost someone who wants to go with her. And by going too fast, she even lost a leg! Just take your time, people.

This was a comment by miracoulus on YouTube, and I responded:

I think you're right! It's a sad commentary about the pace of modern day life and relationships. He wants to sit, and talk, and think ... and sip tea (the epitome of slowness). She has longer legs, and a faster gait, and he evidently cannot stop her, even with just one leg (literally and figuratively). Ironically, as much as she wants to run away fast, she's weighed down by what she's ambivalent about: Having a settled-down, domesticated life with him.
