Helper in the Kitchen

When you're cooking, generally do you like to be alone in there cooking your food items or if there happens to be someone else like a "helper" is it OK? I think it depends on the helper. If it is my mom she will start rearrranging my pots on the stove and saying things like the handle should be facing the other way and not towards the middle of the stove and/or the burner isn't the right one for the pot I have on it. Things like that. I think that is way too annoying for someone to do while someone else is cooking and I'm 49 so I do not need someone telling me how to put pots on a stove, been cooking for years now and I don't bother with minor details like this that are quite unimportant. Yet if I re-wash a dish of hers that is still dirty she takes offense. I'm like, would you rather I just eat with a dirty dish or utensil instead? Gross. Is there anyone you don't mind cooking with? I would think someone who is truely a help and doesn't try to manipulate your every move would be fine or who is clean rather than critical about everything. Otherwise there is no use in having more than one person in the kitchen with me.
