I had to sit in the principal's office for each holiday celebration and all the birthdays.
Sometimes they'd put a chair in the hallway outside the classroom. Imagine sitting there at 6 years old and hearing all your friends whooping it up and you're just slumped down in your chair feeling sorry for yourself.
A few kids made fun of me, but most just didn't understand. When asked why I didn't celebrate I took the easy way out and said my parents wouldn't let me. I hated it being different. I dreaded holiday time. As I got older it became more and more embarrassing to be so different. I would usually miss some school days around the holidays.
I know my parents were only trying to do what they thought was right. And even with that they also tried to ease the pain of being different when they could.
One teacher would wrap a piece of birthday cake up for me so I could eat it later; after the birthday. My mom would keep it for me until the next day so I could eat it after the birthday was over. Pharisaic? yes. But, I'm glad I got to have it.
