I, too, hate shopping with my husband. He likes to come food shopping, and I've tried to accommodate this. We have a small trolley each ... and off he goes - with about 4 items on his list. He takes so l-o-n-g, and put loads of stuff in his trolley that we don't need or want. Biscuits, sweets, etc. When I query anything he says, 'But it's only a pound!' He can't seem to grasp the fact that it's not the money (though it all adds up) it's the space we have to store all this stuff! Added to which, it'll probably all end up out-of-date and in the bin!
(The last time I cleaned out my 'tins cupboard', we had 18 tins of chopped tomatoes!)
Now, when I can, I tell him to have a snooze while I go food shopping on my own. Oh, the bliss! And I'm back within the hour, with just a few bags to unpack. Heaven!
