Invitations: Kommst du mit?
Inviting people is three questions:
- Kommst du mit? — Are you coming along?
- Hast du am Freitag Zeit? — Do you have time on Friday?
- Wollen wir schwimmen gehen? — Shall we go swimming?
Saying yes is easy: Ja, gern! / Gute Idee!
Tip
Wollen wir …? sounds like English "Shall we …?" — the friendliest way to suggest a plan.
