Meeting up S

I met S at 3pm at Taikoo MTR starbucks. With the classes, she looked a bit different from her picture. I recommended a Taiwanese drink at the food court. We walked around log-on and cityplaza to look for a sewing kit, but finally we found the threads and the needles at my flat. I guess her impression about my flat is "small and messy" =p. I also showed her a few pictures taken during my times in the secondary school. She gave me a small gift. This reminds me about S. I suspect if it's a custom in Germany that you have to send someone a gift for the first meet-up. She also invited me for a drink. This reminds me about B. But in my German textbook, there is a strange phrase for bezahlen called "zusammen oder getrennt". I'd say so far I haven't encountered this situation in reality life. The gifts from S and another S
