Things not to do in the third trimester

So the last night I was Boston, I was chatting to a friend on my cell phone. She was stuck in a subway, so had pretty bad cell phone reception. I was packing and it was pretty cold so I was zipping up my sweatshirt. Then the stupid zipper broke.

Bob: How was the talk?
Friend: Oh pretty good.
Bob: Worth being stuck in the T for half an hour?
Friend: What? *crackle*
Bob: Worth being stuck in the T for half an hour?
Friend: Maybe
Bob: Well, give me a call when you reach..oh bloody hell.
Friend: *crackle*
Bob: The zipper on my favorite sweatshirt just broke.
Friend: WHAT!
Bob: I loved this sweatshirt. It was great. It's totally my favorite and the zipper just broke. Damn!
Friend: WHAT! Bob! What's happening? *crackle*
Bob: Yeah, I loved the sweatshirt and it's all messed up.
Friend: Bob!
Bob (clueing in that friend seems rather concerned over a broken zipper): Yes?
Friend: Did you just say your water broke?
Bob: um, no...
