Praying is a very special action. However you will find people all do it differently. Some find they have to pray together, some loudly, some quietly, some alone, some when they need it most, it ranges so much.
I personally like to pray when I am alone, when it is quiet so that I can talk to God. I like it to be privately. The strange thing is that so often I know I pray for people who don’t even give me a second thought at night. Yet I still pray for them. Sometimes I ask myself why do I still bother then? I guess in my heart praying for them to be safe and healthy and it coming true brings me comfort, to know that they are ok is more than enough.
