Complaining friend and minimalist living

My friend, who lives in the group home, was lamenting that she did not have knee surgery sooner. She was blaming the house facilitator of her former group home. I told her that the former manager did help her with her contaract surgery. I told her that it's best to use her energy on the present and future and to not dwell on the past. Perhaps she'll think about it, but if she continues to complain, I will tell her that I don't want to hear it. She calls every evening, and could not reach me one night because I was helping my parents. She said, "Your mom must be really bad, then." She also wants me to bring her fast food on Wednesday and go to the library book sale and buy her paperbacks, both out of pocket. Actually, now that I think about it, I'm not sure I can visit her because my dad will be coming home that day from visiting his brother, and depending when he arrives, I might have to stay with my mother. I also am going with my husband to straighten out financial aid for our daughter next Wednesday. I gained some weight back, so I have recommitted to healthy food choices. The air conditioner repairmen replaced a contact, so the air conditioner is working. My 90 year old dad drove over and was able to get the pop up trailer door open. I realized, probably 7 or so years ago, that I have everything I need to live comfortably in a pop up. It is a tiny little house, quite suitable for 1 person. The state parks have a 14 day limit. I can imagine myself moving my tiny little house from state park to state park, enjoying minimalist living and nature.
