[For a moment, Teddy feels a flush come over his cheeks, and he fiddles with the necklace with a quiet chuckle, a musing smile on his face while he looks down at the table. He's probably reading too much into that "ring size" comment, he knows it, hence why he stays quiet about that.

It's after that moment passes that Teddy lets the chain drop to his collarbones again and looks at his boyfriend once more.]

I was going to say it was cool, not creepy. That you remembered something like that. [A pause, and:] Also, it's cute. But mostly cool.

[Teddy's usually the one who knows "neck sizes" and whatever comes with needing to know how a body is shaped. For Billy to pick up on that with him really is pretty cool.]
