(unless she's an atheist, then it won't make much sense).
I'm pretty sure I have heard many an atheist wish each other Happy Easter where I live. They just say it without thinking.
I am a Catholic but even I get a little tired of the traditional celebration of Easter. I will go to Church on Good Friday and I will go on Easter Sunday but I used to be told I can't do anything that will bring me any remote happiness from Friday till Sunday as I should be reflecting on the sadness. It ended up with me just sitting around the house rather board, hoping for Easter to end [Easter is a pagan name for the Christian holiday by the way].
Lent as well. Jesus had to go 40 days, once. Why do we have to give something up every year? I don't bother now, otherwise it would just be the same stuff, like chocolate or some crap. This year I have given up looking at the KKK site.
