Hello, in my case we can pray anywhere, to pray is to talk to God, I pray as if I was talking to the best of friends God knows your heart and your whole being so talk to Him with all confidence is preferable if you are alone So you concentrate and speak with more freedom about any request, it is wonderful to have communication with God! The important thing is to feel that you are in communion with God and you will see how joy and peace illuminate your life ... BLESSINGS FOR ALL
