I just lived for my last semester of undergrad with two people like this who really got on each others' nerves (all three of us just needed a semester of housing to finish school). They'd both brought their own toasters and just wanted theirs out and the others in a cabinet. I think they had less than 5 conversations in person, instead putting all their incredibly minor complaints in a group text so I'd have to see it. The bathroom just had two towel hangers and they both wanted to hang two towels and would put the other's on the floor even if it was just wet. One would go away for the weekend and try to calculate that they should pay 5% less in utilities for the month because of that. They'd buy something like paper towels and announce that we each owed them $1.50 for that. We had a mail slot and they'd pick up their mail off the floor when they got home and then step on everyone else's.
My only solace is that these people must be incredibly unhappy all the time.
I’ve never had problems like this. I had a policy with flat mates which was. If you put food in the fridge, expect me to eat it, if I put food in the fridge, I expect you to eat it, I’m not going to argue about fridge space or who bought what. It’s not worth the time and effort.
Do you also eat co-worker's lunches? Why is eating what you don't buy an issue?
You'd be spending an evening on the toilet by the third day. And I would have laxatives and air freshener as part of my regular grocery shopping list. This arrangement I would be okay with; you get your food, and I get my entertainment.
Stool samples must be fresh – if they aren't, the bacteria in them can multiply. This means the levels of bacteria in the stool sample won't be the same as the levels of bacteria in your digestive system. If the levels of bacteria don't match, the test results may not be accurate.
If you can't hand your stool sample in immediately, find out how long it can be kept in the fridge. Your GP or the healthcare professional who requested the test will be able to tell you.
I'm guessing you made more than your flat mates. Is it really that hard to remember what you bought? I can understand this for condiments and spices but I'd be pretty upset if someone took something like chicken.
My only solace is that these people must be incredibly unhappy all the time.
