Very interesting! I will never look in shapes the same way again after reading this...looking back, remember asking my mom why my finger nails have a french tip and she doesnt. She replied...it's your dad's finger...yeah, i got it from my father. Hahaha. This is a refresher for me...only recall bits and pieces. Now they're back crowing my mind because of you @luigienius. LOL. thank you for sharing! What an extraordinary thinking! Cheers @luigienius.
