Pride goeth before a fall, and a haughty spirit before destruction (Book of Proverbs, Bible)
In for a penny, in for a pound (I think this is the English pound sterling!)
Pretty is as pretty does
It is better to give than to receive
Charity begins and home
Don't count your chickens before they are hatched
I've been reading the other posts and boy did I hear 'you'd cut off your nose to spite your face' from my mother. Whoa, brought me back. Funny to think that these were the sayings they used to guide our lives when we were kids. I wonder what my daughter would say if I asked her?
