We all express ourselves in different ways.
These feet belong to my good buddy "D". She has the ability to fill my heart with joy. "D" can't speak but she manages to express herself quite well. She has learned a few manual signs but it is her big smile and animated feet that communicate her happiness. You would have to meet her to truly know what I mean because words (especially mine) are not adequate to describe "D". But, if you did have the fortune of meeting her, you would surely leave with a smile as big as the one she most definitely would give to you.
