My Dmum is notorious for this kind of behaviour, bless her.
You can never leave her house, or have her visit, and come away empty handed. We joke that she's Teflon coated. Unpacked after our Christmas visit last week and discovered the reason the car was so overloaded was because she'd 'helped' with the packing, and managed to sneak in the entire contents of her fruit bowl - including a large melon and whole pineapple!
She also drove over to Dsis's house one time to leave half a packet of wooden washing pegs on her front doorstep. The other half she posted to me! Neither of us had mentioned needing more pegs...
She's so careful with with food that she often serves up micro portions. We were there for my birthday last year and she made meatballs for tea. Dsis and I were careful to request pasta because they don't eat it (or rice, bread etc). When we got there she'd forgotten the rice and had tried to stretch a pack of 12 meatballs between six people, so we got two each plus some broccoli :o. Poor DH's face was a picture.
She's a huge fan of the Avon and Betterware catalogues and must send a fortune on utter crap that lasts two minutes. Like the notorious onion keeper
or the microwave egg poacher that either spills raw egg all over the counter (too small, wobbly) or nukes eggs to rubber. The best thing about her catalogue habit is that fact that it's on collision course with her endless guilt over spending money.
She made herself feel better about all the tat delights she bought before Christmas by wrapping it up and giving it to Dsis and me. I got a lovely set of felt Santa napkin holders...
I luffs my mum :).
