It's good to show patience.
Larry is teaching his son Troy math but Troy is having a really hard time grasping it.
Larry wants to comment on Troy's slowness.
"Larry tells Troy ""it's ok, just take it one line at a time, and we'll get through this""."
"Larry screams at Troy ""can't you just get it already? Jesus!"" and slams his hand on the table."
Troy is relieved that he doesn't have so much pressure on him and is happy Larry is supportive.
Troy is intimidated and pressured, so he starts to put up defensive blocks in his mind, further hindering his ability to solve problems.
