Things I have seen denounced as crap (or at least very risky) gifts on Mumsnet this year:
Books
Bath stuff
Clothes
Jewellery
Homeware
Perfume
Ornamental things
Vouchers
Homeware
Experiences
Charity Gifts
Candles
Slippers/dressing gowns etc
Plants
Foodstuffs
Alcohol
I mean wtf is a good gift? And then you run the gauntlet of "not having put enough thought in" and being judged as uncaring for not being able to adequately express your love or friendship through the medium of commerce. Why do we put ourselves through it? Can we just have a collective pact not to bother?
