Rude stranger comment of the month (or possibly the entire pregnancy)

I was at my fave Starbucks today getting an iced tea (seriously, its the only caffiene I drink now aside from the random diet coke) and while I was waiting I was standing next to the counter near two women who were also waiting for their drinks. I was wearing one of my pre-pregnancy hoodies, and while I was waiting, decided to partially zip it for whatever reason. As I was doing that one of the women makes the comment "I feel sorry for that jacket!". Are you effing serious. It was tight, but not THAT tight...like the zipper was fully intact and not about to rip or anything. And then her friend was like "I think she's pregnant, but she isn't supposed to have caffiene if she's pregnant" OMG, seriously. They weren't being quiet. Its not like I couldn't hear every single word they were saying, and I knew they were talking about me. If I wasn't so hormonal and emotional the last few days (to the point where I would have started crying if I had to say anything), I would have gone off on them. Who the hell does that? Biatchy women like them. And this is all the day after I was at the hair salon and had 3 different people ask me how far along I was, and were all shocked I am now 7 months, they all didn't believe that I was that far since I'm not HUGE (at least not in the last few days). I really freaking hate people now...
