One of the more typical Lenten practices (in terms of the "prayer" dimension of the traditional triad of observances) is an increased recollection, usually sought through forms of silence. For some people, this means being more alert about occasions of gossip, and pulling back from conversations moving in that direction. This year, I am noticing a new form of Lenten recollection: people are giving up Twitter for Lent. (There may be a few hardy souls who are going cold turkey on all forms of social networking, but so far I haven't seen any notices about people giving up Facebook!) If my mission didn't involve these forms of communication, I would probably give this greater consideration... although I certainly could moderate my interactions a bit more!
Do you have a particular Lenten form of recollection that you try to practice? What is it?
