Dear Parents,
It is THAT time of year--again!  We all see a 27 day finish line and it's compounded by the fact that students have been in the same seat, in the same room, with the same contemporaries for eight months. They have been masked and separated; have had to give up some of the fun STM traditions like Oktoberfest and Prayer Partners; and they long for normalcy. The weather is warming and the sun is out, causing rising temperatures on the playground and rising tempers in playmates. It is the time of year when we notice less kindness and more isolation, less compassion and more passion. But we are promoting fist bumps rather than fist-a-cuffs, high five’s instead of high kicks, and many pleases/thank yous and I’m sorrys. Please have the conversation with your son(s) or daughter(s): Christ gives us the model to follow. Kindness at all costs!
Golf tourney is filling up. Be sure to register your foursome before all the slots are filled. We have lots of great sponsors, prizes and a scramble format that will guarantee everyone has a great time. Just a reminder that this is an adult event as contracted with Army Navy Country Club.
Chat soon,
