ANN I hope you have a nice visit with your cousin. I can only imagine how emotional it will be. I always cry when I see my Aunts, my mom's sisters. It's a shame we never realize when we are young how important those relationships are with extended family members.
I have 2 cousins that I was close to and have tried endlessly to get them into the family again for holidays and such. One is NOT interested at all. The other has health issues she uses as an excuse. Her own Dad keeps after me to keep inviting her. Her dd loves to come see her cousins. She was so cute the first time she came over. She hugged all her cousins and danced around.
Enjoy the day and do take some pictures.
