Dear Catherine,
Good morning from Austin, Texas! School started today and I am starting to like this very much. Part of this is due to my amazing teacher. She's nice and sweet but teaches, well, stopping to keep all students on the same track. I feel as though we can talk about anything with her as well. I was talking about something totally random during class and she seemed understanding, even connecting it back to the main topic. I am so blessed to have gotten such an amazing, dedicated teacher.
Miss you,
Amy
