While cleaning out my scrapbooks and bins of paper, I found many birthday or holiday cards addressed in my grandma’s handwriting. She always wrote “Master Kyle” or “Miss Megan” on the front – quotes included with her script.
Then on the card itself you’d often find the titles or greetings “evened out” so that they were fair to all the cousins and siblings. If my sister’s card was printed with “To A Wonderful Granddaughter” you can bet mine had Wonderful handwritten in with a ^ carrot symbol to make sure there was no playing of favorites. Or if she found a greeting she liked but it wasn’t specifically for a granddaughter, that wording would also be edited or added to convey the exact sentiment she was trying to express.
I’m sure the postmaster has frowned at me plenty of times as I’ve used “Grandma” in the recipient field of a mailing envelope instead of her full name or legal name. I suppose for the most part, it always worked out because we’re not in a big city and the package isn’t arriving at a destination with multiple tenants who live there.
Do you have a specific way of writing out the person’s name and house number? Does your scheme change whether or not the card travels through postal mail or is hand delivered?
