We (4) ______________ (not have) a lot of money so I was really pleased for them. But things soon started to go wrong.
Gary, a lad I (5) _______________ (see) at the time, told me he (6) _______________ (not really want) to talk or be seen with me because of what other people might say or think. He thought that everyone thought he was with me for my mum's money!
