A while back I started doing something new during group prayer times.  I kind of did it out of necessity at the time, but I have continued doing it and I really like it.

When I'm in a setting where we are praying together in a group out loud, I can find myself being distracted.  My mind sometimes wanders and I realize I have missed several sentences of someone's prayer.  No matter how hard I concentrate this seems to happen more often than I'm happy to admit.
