I tell my DDs I will love and support all their choices except the following, which would disappoint me:
a) Ever being financially dependent on a man, changing their name on marriage or being 'given away' at a their wedding
b) Voting Tory
c) Being rude to servers/shop floor staff
Beyond the obvious list like not committing murders, what very specific things would upset you? (This is a bit lighthearted and obviously very personal to each of our values)
