8 women of different heights are at a party. Each woman decides to only participate in a handshake with women shorter than herself. How many handshakes take place?

This is a strange one. The answer was totally unexpected!

Assuming A is taller than B and A dicides to shake hands with B then B refuses because A is taller.
So 0 handshakes.
If this restrcition is taken out then you have
7+6+5+4+3+2+1 = 28

Yep, you got it right. 0 it is. I had immediately answered with 28 without thinking it through.

Thinking is indeed the key.
