A have-to-share

After I drop Truett at preschool a lot of times I stay for a minute or two and spy on him to see how he's getting along. When I went to pick him up today his class was in the gym so I could see him through the glass doors for a moment before I walked inside. I froze. There he was on a little push bus sitting as still as a statue while another little boy gently tried to put a barrette in his hair. I just wanted to squeeze the moment.
