Hi Lgastreich,
You are too funny. Go get those slouchers! They will all look like angels in no time. But remember, you are still in early recoup, and God knows and will totally understand if a of your angels are a little crooked, so long as their songs and words are in his spirit

Glad you discovered the Golfer's Reach. It was, and continues to be my savior. We are conditioned to think we have to bend forward at the knee and squat to pick up, tie, etc. I learned with my THR that bending at the waist/bad leg straight back is not only perfect for hip recoup, it's better for your back. I use it now all the time to avoid a reoccurance of sciatica/ to avoid other back issues.
Tying Shoe laces was a biggie for me too. If you still have this challenge, or for those reading who do, try this.
Put the lace shoe on you op leg. Stand with your butt facing the bed. If needed, hold on to the bed table.
Bend the operated leg back at the knee and wiggle your foot up on to bed. Goal: Instep flat on the mattress with your heal facing the ceiling.
Bring in your toes a bit to lift your instep up and release the laces.
Lean down as if to sit on your foot but do not sit. Lean just enough so you can grab the laces with your two hands.
Tie.
This stance maintains the 90o and worked like a charm for me.
I started with the elastic curlie laces that do not need to be tied (just need a pull to tighten). Gradually I learned how to tie regular laces backwards.
If you just don't have enough flex, stick to the elastic laces = just pull to tighten. They look like curlie cues, sold as kids laces. Found mine at Payless.
... and then, there's always slip-on sneaks (lace less).
Hope it's clear to you and all posters!
