There are many different sorts of prayer.
Sometimes prayer is divided up into (ACTS) Adoration, Confession, Thanksgiving, and Supplication. Sometimes people simply try to be silent and remember that they are in God's presence.
Sometimes prayer is a short heartfelt petition (an arrow prayer) or even a cry or shout of agony or longing. Sometimes we can pray together. Sometimes we pray alone.
Sometimes prayer is done in church. Sometimes prayer is something done as we travel to work, tidy the house, walk the dog...
