Can u believe what happened to me in church last sunday??

I was at M last Sunday, Oct 21st. When the congregation started singing a hymn towards the end of M, I leaned over to speak to my husband about stopping at the Gift Shop in the Narthex to purchase a St. Christopher's medal for a friend of mine, when out of the blue, this man next to me rudely said to be quiet or why don't I take it outside!!! What do u think of this?
