T initiates handshakes and, after I first asked for a hug, he would occasionally ask if I wanted one after a tough session. Now its just an every time thing so no one really initiates it. There have been a few times when I am particularly disconnected after a session though where he won't let go and encourages me to give him a real hug. Those moments usually end with me in tears but it's comforting to feel like he cares in those moments.
