Some people grin and bear it; others smile and do it.

I like a man who grins when he fights.
Winston Churchill grin quote

If you have only one smile in you, give it to the people you love. Don't be surly at home, then go out in the street and start grinning Good morning at total strangers.
— Maya Angelou

Something of a person's character may be observed by how they smile. Some never smile they only grin.
— Christian Nevell Bovee

And the Devil did grin, for his darling sin is pride that apes humility.
— grin quotation by Samuel Taylor Coleridge
