For me, it is taking the rubbish out. We compress it and compress it until it is the density of lead. One of us will then cave... usually my husband. If I try to, it is too heavy for me to lift by that stage!
But... My mum is coming to look after the kids today and I didn't feel it was fair to involve her in my pettiness so I just took it out. Taking out non-compressed rubbish is, I discovered, a dream! Easy to pull out, nice and light. Easy to put in the dustbin, bag didn't split, room at the top to hold the bag, rather than sort of hugging the rubbish.
What a revelation!
