Something I am thankful for that starts with the letter "P" is........
Plants, pom poms, pansies, petunias, ponies, potatoes, peonys, pink glitter, pink carnations, pussycats, perfume. 
I saw "glitter" and was like, "hey, that doesn't count!" but then I realized it was the second word in a two-word answer. I forgive you. LOL
Phones, porn, pb&j sandwiches, pens, peach (the color) , pigging out,
Peonies, (care) packages, passion, physically fit
Photos and photography, photo albums...
My Pappa, that he is still alive and that I can enjoy time with him.
