Does Arnold have supportive parents?

Arnold kinda has supportive parents when is comes to devastating moments.
I know where he is coming from when he says that his parents don't say "I love you" to him that much. I usually say I love you to my parents when I am leaving the house for awhile. At this moment in the book his parents say "I love you" because his sister died and his mom doesn't want Arnold to leave her. Arnold obviously has parents, but he is probably scared to go up to his mom or dad and ask questions and to tell about his day. If I had parents like that I would somehow go to the parent that is the most supportive and wanting to hear about my day.
