Dear Ruth,   Thank you very much for the lovely present you sent for Laurie. It was very kind of you. You say in your note that you haven’t got used to being (be) an aunt yet. I used to think (think) that becoming father wouldn’t change me. I was wrong, of course! Life will never be the same again. We used to _____ (go) to bed at midnight or later. Now we’re asleep by ten because we’ve had to get used to _____ (wake) up at five o’clock. Actually, that’s quite good in a way. I always used to _______ (arrive) late at the office, but since Laurie was born my secretary has got used to ________ (find) me hard at work by the time she gets in! Mind you, it hasn’t been so easy for Jenny. I think she found it very hard first, being with the baby instead of going to work. She wasn’t used to ________ (spend) all day without adult company. But she’s got quite friendly with a neighbor who also has a young baby and I think that makes it easier. She used to ________ (say) she’d go back to work when Laurie was six months old, but now she’s used to ______ (be) at home she’s beginning to enjoy herself, so she may wait until Laurie is a bit older. Anyway, when do you think you’ll be able to come and see us? Jenny says hurry up, while Laurie is still small. We’d love a visitor to show her off to! All the best, Dennis
