Clean Monday is the very first Monday which begins Great Lent, and it is a quite somber day on the spiritual calendar. In Greece, it is customary for young and old to fly kites. We have been encouraged to give this activity a bit more meaning for the soul here in America, possibly the day or two beforehand, with the following activity.
On the Sunday evening before we begin Great Lent, there is always held the Vespers of Forgiveness where each parishioner asks the priest and one another for forgiveness. It marks the beginning of a great journey in which we embark to clean our souls of the darkness built up from our sins. Consider gathering your youth (ages 2-18) and even their parents earlier that day, or the day before to set aside for Confession and Kite Flying!
The younger children can prepare and experience Confession as a group with the priest, who can speak with them openly about the topic of sin and all can kneel under the "epitrahelion" for the final absolution to conclude, whereas the older kids can prepare their confession ahead of time and meet with the priest one on one. As each group finishes, we all meet outside to hand out free kites and experience the "joy" of a soul released to soar, free and lightened from the burden of sin!
