you and Sherlock where married, at the moment you were at a trip in Italy for a case and where going home tomorrow so Sherlock wanted to have something prepared for you when you got back since it was also your anniversary that day..so Sherlock was with John and Mary at the shops trying to rule out what they think will be good gifts for you.

Mary:,”maybe taking her to dinner would be nice.”To which Sherlock countered with, Sherlock:,”she will be exhausted from the plan ride I doubt she would want to leave the house.” John:,” maybe some jewelry?” Sherlock:,”that’s to common.”
