two quick thoughts
1. It is good to be down once in a while. Those are the times you cry out to God and are closest to God (or at least trying to be).
2. We try to relive the past by visiting the places we grew up in and doing the things we used to enjoy but find no joy in any longer. But there is a link to the past, and it is very much alive, unlike the dead memories we try to resurrect. It's prayer: the thread of prayer is the link to the past and to the future. We prayed as children, we will pray when we are old, we pray now--it is the one living link.
