They were four or five, maybe six months old when we brought them home. Watson hide in the basement for a week. The greys stayed under the couch most of the time. They came around eventually. Watson can be very demanding at times, but typically spends all day up on the bed. Mycroft will drape himself over my wife's shoulder for hours while she's on the computer, but he still runs from me. Sherlock and/or Mycroft will sometimes nap with me, but only balled up behind my knees. Anytime we go in the bathroom, Sherlock will jump up on the sink and look plaintively begging to have the water turned on a trickle so he can drink it. It doesn't matter if you just put a fresh bowl down, he wants to drink directly from the faucet.
