Look at the irony: we spend weeks teaching the 2nd grade children that the Eucharist is an amazing gift from God, and that every church has the Eucharist kept in the Tabernacle, and that, when we are in the presence of the Tabernacle, that Jesus can see and hear us and we can speak to him. We teach them that the day they receive their 1st Holy Communion will be a truly special day, and that they should behave in a way that shows they understand it is a special day. We rehearse them to walk in a solemn procession, to keep their hands folded together in a prayerful gesture, to stand and sit and kneel at the proper times, to receive the Blessed Sacrament properly (either tongue or hand), and then to go back to their seat and reflect on that great gift in silence. Of course, we tell them not to spend the Mass speaking to the children on either side of them.
Then, the day of the Mass comes. The kids are fine. The grown ups? THEY SUCK!
I'll leave it at that.
