Teddy/Calliope
Not at all! I think it's a very cute thing my parents do for each other all the time. Mum's got all of them hidden away somewhere in my normal time. Besides, you never know when they're having a bad day and might find one, and it'll make things better.
The only Black family members I always knew as Black were my Uncles Sirius and Regulus. I always wondered what happened in that generation, because it seems like most of them, save maybe Aunt Narcissa and Aunt Bellatrix, wait I'm not supposed to talk about her really just had enough.
