preschool graduation picture

i took pictures of each 4 year old in hannah's class in their caps and gowns today. i wanted to cry seeing them all, looking so grown up and knowing that they'll all be going to different kindergartens. she has known most of these friends since she started going to preschool last year, and kids change a lot from 3 years old to almost 5. i just know i am going to cry and cry and cry when they have their graduation in a week.
