After not seeing someone for a while

1. I was just thinking about you.
2. We have a lot of catching up to do.
3. Let’s pick it up where we left off.
4. Long time no see.
5. Where have you been hiding yourself, it seems like you dropped off the face of the earth.
6. It’s been a while, hasn’t it?
7. Welcome back, it’s so good to see you.
8. I haven’t stopped thinking about you since the last time we got together.
9. It seems like you’ve been gone forever.
10. Absence makes the heart grow fonder.
11. I missed you.
12. How have you been doing, stranger?
