....claim for oneself. Right up there with "I try to be kind to others" and "I try to listen to other people"
Good for you.

but how do you know who is Muslim?
I don't say Merry Christmas. I say Happy Holidays.

I say "Eid Mubarack" to both the husband and the wife when they're couples.

I'll try to remember that.

I'm a total atheist, but I do the same. The owner of the gas station I go to gets the biggest smile when I say it. And this year, I talked to him and asked a few questions about their Eid feast. He just was going on and on about his wife's cooking and he just really looking forward.

I asked him where he was from and his eyes saddened a little. "Palestine." He answered. I said, "Oh, my friend, I am so sorry. I have no words to help." I said, "Just know that there are some of us who want a peaceful resolution and a homeland for both Palestinians and Israelis." He smiled again and said, "Yes. We can live in peace if we choose."

As I left, I said, "Assalamu alaikum!" And he replied, "Walaikum Assalam,"

And as Passover begins for my Jewish friends this Monday, I say, "Chag Sameach!"
