An extra class pet?

I have a dwarf hamster class pet whose name is Canela (means cinnamon in Spanish). The kids love him, and he is mighty cute! Today while I was in the middle of my lesson my eye caught something else running towards my desk. While some teachers would have shrieked and screamed, I thought it was adorable and was curious to meet him. I finished up the lesson and tried to catch it so it wouldn't get stuck in the mouse trap. It was next to my desk and it stayed there almost all day. He was sooo very small and he was sooo cute! So, it's the end of the day and I come back from car duty and I hear screaming from the teacher next door. It seems the lil' fellow paid a visit to her as well, except she wasn't as welcoming as I was. They caught him and put him in a container. We asked one of the kinder teacher's grandsons to take him outside of the school. He literally opened the door and let him out. Not exactly what we had in mind, we were thinking as far from the school as possible.
We had a baby shower for a couple of teachers today after school so we were all down there for over a half an hour. Punch, cake, open gifts, and watching the clock go by. I was so tired today and felt a little sick. So I went straight to my room after it was over so I could get my stuff and leave. As I leave the school, my little tiny mouse friend is there waiting for me RIGHT by the door. So well mannered huh? Haha... anyways I couldn't just leave him there. I didn't want anyone to kill him so I went back in to get a bag so I could catch him and release him to the grassy fields. While I was trying to catch him you can tell he was scared poor baby, he even squealed (I know pigs squeal, not mice, but it was this high pitch cry of help) it broke my heart... I know only I am this concerned about the mouse's well being. I mean after all, where is its Mom ya know?!? I finally caught him and walked away from the school. I held him up in the Ziploc bag, he was soooo cute seriously, he was so teeny tiny! Anyways, I open the bag and let him out. He just stands there... I think he was so confused. And he was so little he probably doesn't know what to do out in this big world all alone.... :( Well, it made me sad a bit, but I had no other choice. As much as I wish I could have another class pet... I don't think a wild mouse would go over too well. I hope he is well and that he finds some food and smart like Ratatouille, haha... ok a little extreme but the little fellow must be scared ya know so I hope he is ok. So that was my good deed for the day, I saved a LIFE... a mouse's life but hey... it counts right?!?!
