If he likes it and helps him feel independent I wouldn't interfere.
It is nice of you to offer to go to walmart for huge bundles of TP or paper towels etc.
My loving son is a lifesaver. He has been staying with me until the addition is complete. His uncle (My X's brother) is adding onto his 4 br, 2.5 bath home. In fact, my son will be moving into his new room probably next week, that his uncle just added on. He added 2 more bedrooms and another full bathroom. His uncle owns his own insurance company and coaches high school baseball and football. My son helps him when he needs him. I coached my son in baseball from age 4-13. He was on each team I coached back then.
So, my son came here and told me that he would help me in any way he could. Oh, he visits quite often, but it's so nice to have him here daily, even if it's for a short period of time. I usually order can goods, crackers, spaghetti sauce, etc., from AMAZON. I get all of my dairy products and such from Wal-Mart. But, I think I will be ordering from Wal-Mart in the future. Does anyone here order from Wal-Mart? Opinions, please?
