Jim listened, only making one face when he initially mentioned stealing a summer home. He would do that even without any sort of future plans, purely to annoy the Holmes family - mostly Sherlock or Mycroft. The rest of it didn't sound so bad either. He can't even find something to poke fun at.
"You're absolutely adorable, Sherri." The smile that stretches is warm, shockingly genuine too. "We wouldn't need your family summer home, but I'll take it for you."
