Simple) hard work, and the hours (to be, Pres. Simple) really long, but I (to like, Pres. Simple) it. And it's well paid. The office is really relaxed. No one (to wear, Pres. Simple) a suit or a tie. The only thing I (not, to like, Pres. Simple) about this flat (to be, Pres. Simple) one of the neighbours, Mrs Shell, I (to think, Pres. Simple) her name (to be, Pres. Simple). She (to be, Pres. Simple) really strange. She never (to speak, Pres. Simple) to anyone. I always (to say, Pres.

I (to have, Past Simple) a party a few days ago. It really (not, to be, Past Simple) very noisy. About ten of us (to be, Past Simple) here until 11.00 and then we (to go, Past Simple) out to a club. When I (to see, Past Simple) Mrs Shell the next day, I (to say, Past Simple) I (to hope, Past Simple) there (not, to be, Past Simple) too much noise, but as usual she (not, to say, Past Simple) anything. Funny lady. This evening my sister and I are going to visit a friend of ours who (to be, Pres. Simple) in hospital, and then we're going out for a Chinese meal.
