Want in on this debate? It's of vital importance...

I started this text debate with my family this morning... lot of opinions but there was a clear 'consensus' answer from my family....whether or not they're right?

I've been wondering about this for years.... which will show you how shallow my life is.

Why are today's bars of soap, (most of them), concave on one side and convex on the other?

I don't like it. Makes no sense to me.... even if my families consensus answer is correct (which I'm not revealing here so as not to bias you..... ummmm, should you reply to this debate which is probably very unlikely).
