While not officially an atheist, I don't exactly understand your question.

Say GoodBye, see you later ... why not.

Celebrate a holiday, presidents day (OK teasing).

Most religous holidays have become so commericialized they bare little resembalance to the days they are meant to be.
Look at Xmas.
I don't really celebrate Xmas (the Wife drags me kicking and screaming through the process) as Xmas, except as a family get together.
Which is always something to celebrate, family and friends.
