Do you get anything for your girlfriend or wife today?

I hear Valentine's day is in the form of a man buying something like flowers or candy for his girlfriend or wife.

Japanese Valentine's day is totally/complete opposite to western countries.

You know, a woman gives a present to a man.

Do you have any particular feelings what the UK and the US are complete opposites?
