I'll make this one short and sweet. I live with two of my close friends. Let's just call them 1 &amp; 2. So 1 &amp; I decided to order our groceries through an app that'll have them delivered to us &amp; split the total. We asked 2 if he wanted to add anything to the cart and 2 said "Nah I'll go to Walmart and get food I'm good." So 1 &amp; I left it at that. 1 &amp; I ran through the food and decided to place another order a few weeks later. Same thing happened. 1&amp; I filled up the cart with essentials, and then asked 2 if he wanted to add anything and split the total with us. 2 said "Bro nah that place your food shopping at sucks. I'm good" then 2 got up and walked out lol. So I get home one day and see a little bit of smeared jelly, crumbs, and an opened loaf of bread on the counter. Turns out 2 made a PB&amp;J sandwich with 1 &amp; I's bread. So I text 2 letting him know I would never turn down food from someone, ever, but if 2's going to be eating anything 1 &amp; I paid for than 2 has to pay part of the grocery bill. 2 was exclaiming "it's only bread peanut butter and jelly why are you taking it so serious?" &amp; I was tryna explain to 2 that it's about the principal of boundaries. You don't shit on food in any way, especially two guys food shopping who are asking you if you want to split a bill and save money and say "Nah that place sucks" then turn around and eat food that came from that same establishment you said sucks a day ago. I had to tell him all this plus, please don't touch the food unless you've put money towards the bill or AT LEAST ASK one of us to make a sandwich. Now he just orders dominos every night while we cook and eat the craziest meals every day. I feel like an asshole cause he won't eat meals with us anymore but he did it to himself though.
