OMG it's so funny, but a little gross, that you heard your house guests doing the nasty!
It's awesome that you got so much yard work done!
It must have felt very rewarding. It sounds like a good way to keep yourself busy. I would get a pair of work gloves so you don't get blisters on your hands, and they're good for pulling up weeds, too. You can pick a pair up at a hardware store. They're very cheap. It was very nice of your friend to help out.
I'm sorry that the landscapers cut those shrubs/bushes too short. They should have known better. They should grow back tho... hopefully quickly.
I'm sorry that your hip is bothering you again. I hope that it is better today
