We had a good number of posts for height. Maybe a good chance to take a look up!
The prompt for the rest of September is the letter U. Please use U for your label. But it might take a bit of lateral thinking!

and a Certain Dog who likes to sleep upside-down.
Looking forward to see the U things you can find. Will it be a stretch?
