The logic of your post Indigo8 is that we should not celebrate anything, ever. Because whatever you celebrate, someone willl feel left out, having a baby, a wedding, a birthday - a _relation's birthday, everyone has dead relations - or none, Valentines day, Mothers, fathers, grandparents days, exam results, getting a job, retiring, of course all festivals like Christmas, Easter and all other religious festivals each and everyone is bound to upset someone.

On the other hand the snow flakes of this world could just swop their willow spine for one of steel and accept that as we go through life, every so often when they are unhappy others are happy, just as when they are happy, others are sad.
My sister died on Easter Sunday, the next Easter Sunday we were a bit subdued, but then we got back to normal. Yes, we all remember DS died on Easter Sunday, but then we tuck into the chocolate eggs.
