I understand what you mean. I've shed a lot of tears over silly things. And gotten upset for ridiculous reasons. You were probably tired from Calvin too. Ok, here's my story, it doesn't involve as many tears, that's two million other stories I don't need to mention. Well, anyway, it was at the camping trip. I was tired. I had left my backpack and some other stuff on a table and Rebekah had asked us to move. I wasn't paying attention until she called out she was going to auction it off. That made me mad. I threw my stuff on the ground and was like, THERE! HAPPY? I just about screamed in her face, I was so upset, but for some reason I didn't. I'm glad I didn't cuz then all of the sudden I realized I had hardly any logical reason to get angry at her, she was just trying to get people to move her stuff and wasn't intending to hurt people. And then I realized how terribly mean it would have been for me if I had yelled in her face and I started to cry a little. It was very upsetting.
My story's different, but I think its encouraging to know that we all have these terrible angry teary moments. We're there for you, God's there. You know, sometimes, it feels almost good to cry, like letting loose your emotions to the wind and ridding the frustrating feelings that you're holding inside. Don't worry about crying, sometimes it happens, and sometimes it helps!
