My husband and I were having this discussion just this morning. I used to *never* accept help. I wanted things the way I wanted them. Period. I'm not a control freak about much, but I can definitely get my cook-zilla on when trying to execute a party or holiday celebration.
I finally relented a couple years ago and decided that I would accept the gracious offers to help. When it came to grocery shopping and prep, I loved the idea. It was so nice to have a much shorter to do list.
It was all good, of course, until they arrived with said dishes and I was bombarded with "Where should I put this? Is there an oven I can use? This needs to warm on the stove." Or worse, when they had to GET INTO MY KITCHEN to cut, slice, garnish, whatever. i think I almost lost it when my husband's aunt offered to bring the relish tray and walked into the house with jars of pickles and olives in a grocery bag. Not only did I have to stop and find her a tray, but then we needed to find room for all the open pickle jars.
Yes, I know I sound like a curmudgeon, and the offers to contribute are very considerate. I just don't want them in *my* sandbox. KWIM?
