I'd keep Stitches (I wasn't sure if the poll meant who to keep, or who to let go of, so I voted Beau since it seemed like you meant which one to let go of?)
Deer is my favorite animal villager in all of animal crossing, and I already have Stitches, and am planning on getting Beau as well, BUT. Stitches is waaaayyy to cute. If anyone, get rid of Beau. It's just impossible to let go of Stitches. I could never do that. </3
I love that little bear. I've had Beau previously too and he is adorable, but Stitches is all tiny and cute. I eventually got a bit bored of Beau but Stitches will be a permanent villager.
I think I voted wrong, I voted to keep Stitches when it looks like I should have said to let go of Beau. Sorry about that
