Mob's attitude seems to change once he hears what Dimple says. Mob ends up apologizing to Dimple because he had gotten carried away from the thought of being popular and didn't hear what Dimple had to tell him before.
The fact that he could never
fully commit really annoyed me, too.
حقيقة عدم التزامه الكامل استفزّتني حقّاً أيضاً
Dass er sich nie ganz festlegen konnte,
hat mich auch genervt.
Su indecisión me indignaba,
Su indecisión me ponía enfermo,
était toujours indécis
E poi la sua incapacità cronica 
di dedicarsi completamente a qualcosa mi dà sui nervi.
E ele nunca se dedicava completamente...
Как и о том, что он слишком мягок.
