Yep, I celebrate it with or without a partner. I make treat bags to give to my girls and people close to me (this year it was white chocolate chex mix), and my sister started hosting a scrumptious annual Valentine's Day dinner party which I attend. I consider it a holiday about love. All kinds of love.

First of all, Valentine's Day is not a religious holiday.

I don't have a romantic partner but I celebrate February 14 as a friendship day with close friends, my students and my grown up chiildren.

Ask yourself, do atheists love others ? Of course.

Do they ALL observe Valentine's day ? Some do, I'm quite sure.

I wear a little red heart pin on my shirt on this day, and proclaim to anyone that comments : "I have a heart on !"
Always makes for giggles ... and cheers folks up - including myself . : )

It's not a religious holiday

I don't know of any theists who would consider it a religious holiday, even though it's named after a saint.

Like every other holiday! I wish my female friends Happy Valentin’s Day, send Mom flowers and take her to dinner. Sent an online card to my ex, who I am still friends with and love. But I don’t take it anymore seriously than Easter .
That being said Happy Valentines Day! Love of any kind should be celebrated!

With, and ignore it.
