She really did join the army

My sister hid it from us that she was joining the army. Well after she told us and we knew she should be in boot camp mom called her house. Or something like that. Well she told mom that she was home from bootcamp for a visit cause she has kids. We all said no way is that happening. They don't care if you have kids. Well mom just got a letter from the church saying that she is in the army and actually going to church down there. we are shocked that not only is she really in the army but that she is going to church. Maked me wonder what she thinks she can get out of it. I love her to death but she thinks of herself alot.
