1) "Прекрасно пообщались"
Самый простой и безотказный вариант - поблагодарить собеседника:
- I've really enjoyed talking with you.
- I'm glad we got to talk.
- Thank you for your time, it was lovely chatting.
2) "Не буду больше задерживать"
Вы очень пунктуальны и цените чужое время? Тогда запоминайте:
- Perhaps, I should let you go.
- I know you're busy, so I don't want to keep you.
- I will let you know!
- Great, have a good afternoon!
3) "Ещё увидимся"
Если вы не против продолжить разговор в другой раз, упомяните об этом:
- Well, I'm sure we'll see each other again.
- I would like to see or hear from you again soon.
- So, let's talk again soon.
- Let's meet again.
4) "Мне надо бежать"
Пора заканчивать разговор? Сошлитесь на действие непреодолимой силы:
- Excuse me, I need to make a phone call.
- Sorry, I've got to run (have to go now).
- If you'll just excuse me, I need to go and say hello to someone.
- Anyway (well/so), I should get back to work.
