person A: I'm expecting a friend who I haven't seen in years to come over tomorrow. I'm a bit nervous about seeing him as I'm not really sure how much may have changed since the last time I saw him.
person B: It's exciting that you will be able to reconnect with an old friend. I understand that you're nervous_comma_ though!
person A: Yeah I think so. I usually get nervous before social situations so I guess I'm used to feeling this way anyway.
person B: I'm sure once you see each other and get to chatting it will be like no time has passed! Have fun!
