I bet, with girls, it's more the social and hormonal stuff. My parents tell a story of how we were all having dinner one night and my dad said something in conversation and I burst into tears, stormed from the table and ran to my room and he had NO IDEA what happened.<quoted text>
I can only speak anecdotally, but my parents and grandparents, who have raised both, disagree with that statement.
There are issues and challenges with both.
