Tenzou didn 't have a lot of friends. Actually that statement was misleading. Really Tenzou only had one friend but Kakashi-senpai was busy quite often with the solo missions assigned to him that the rest of the team didn 't get to go on. When that happened Tenzou was usually left alone. He had only joined ANBU a few weeks ago and so far he didn 't quite fit in as well as he would like to. Growing up in ROOT had stunted his social skills and his ability to connect with fellow human beings. Kakashi-senpai helped when he could but he wasn 't that great at it himself, to be frank.
