In the followin conversation, there are some phrase that I couldn't undersatnd.
|Laurie:||This was a very good meeting, Liz.|
I'm happy that we've finally cleared up some problems.
I think we have. Is there anything else to discuss?
No, that's all, I guess.
Then, let's call it a day, shall we?
All right. See you later, Alligator.
After a while, Crocodile.
1) Let's call it a day => I think it means "Let have a day off", but I can only guesss here
2) alligator and crocodile, => they are the same meaning...but why do they call each other with the animal name?
3) after a while => I think it means "see you later"
Am I right?
Thanks in advance.
