for me, I think it is his lack of appreciation for anything. not just his material goods, which he definitely does not value whatsoever, but the simple things in life: a roof over his head, food in his belly (despite his constant whining about being on the brink of starvation), people on twitter who still value him enough to try to give him encouragement or a kind word, the companionship of his pets. everyone has troubles, but most people, if asked will be able to name at least a few things that they are thankful for. whereas Lou, if he is asked directly to name something he's grateful for, will deliberately say "nothing." just to fish for more pity, as though in a world full of war, sickness, misery and human cruelty, he alone is suffering so greatly that there is nothing in his life worth celebrating.What do you guys think is Lou’s worst trait? He has little to no redeeming qualities but what do you consider to be his number one vice
Personally, I feel it is his pathological lying.
