I noticed when i was Christian and going to churches, we met in church and talked a little but when i saw them in Public...they never spoke to me.
But when i would stay with a Pakistani-Canadian friend & his family, we would be in public and people would always come up to him & his sisters with salaams and a smile. I would ask 'Who is that?' and they would reply 'Not sure, someone from the Masjid' It was really sweet all those people would recognize them, not know them but still approach them.
I am not a regular member of a Masjid yet, does anyone else have similar stories?
