Speaker 1: My youngest child started high school this year. It really made me think back to her starting kindergarten, and how time really goes by. I can just see her learning to read!
Speaker 2: It is so hard and so rewarding to see them grow up. 
Speaker 1: Yes, it really is bittersweet. But, the older they get, the easier it is to think back to the younger days!
