What happened on September 11th?

Was shocked tonight when Tricia shared with our Small Group that the 1st grade students that she teaches were not even born yet on September 11, 2001! Mrs, Kaye, what happened on September 11th? Wow! Someone else at Small Group tonight was telling us that they were teaching their 6 year old son about 9/11.

Am I the only one that finds this crazy!?! Time flies. I cannot believe it has been 7 years. I pray God's peace today for those impacted.
