Hi! So as many of you know, my mother had a hip transplant 6 weeks ago but unfortunately developed many complications. She's back in the hospital with blood clots in her lungs and legs now. I'm going to post this puzzle today because I also have her dog at our house and it's a bit chaotic today. If you have anything for Friendship Friday, please email me at email@example.com.
