I remember when I was on the verge of breaking up with my ex a few years back. Everything he did annoyed me, he was a very self centered, egotistical guy. One of the last few dates we were on, I had my tumbler in the car with the plastic straw. Well he broke said straw and I was so upset lol, I never get mad about things like that. But the fact he was already on my nerves, you could say that was the last straw ;)
