Try and bring to mind a particular Thanksgiving dinner. Where did you go? Who was there? What events stood out in your mind? Write the scene so that all of the senses are involved: sight, smell, taste, touch, sound. For instance, is it the crumbly texture of your grandmother's pie crusts that you remember most? Maybe the smell of your uncle's cologne which overpowered the cooking food? Did you always have to sit next to your squirmy cousins at the little kid's table and start to feel claustrophobic after awhile. Was this the only time your mother brought out the good dishes? You'll be surprised where these memories lead you, whether it be to an emotional awareness of something you'd forgotten or perhaps never realized!
Whatever your memories, let's be grateful!
