I wish people in forums could use basic English grammar. How many people know that the past tense of the verb 'to buy' is 'bought'. NOT 'brought', which is the past tense of the verb 'to bring'. AAAHHH!!!
Some examples:
"I would like to buy a new PC."
"Yesterday I bought a new PC."
"Should I bring my girlfriend to be a sober driver at your wedding?"
"I brought my girlfriend to be a sober driver, but she got stuck into the champagne and is now so drunk she can't stand up!"
Cheers
