Not at all. It's because 'e' is both the button to start a conversation and continue it...so if a conversation is long and you want to skip to the end ( maybe because you've read it before), you'll keep pressing the button repeatedly and accidentally start the conversation over again...and loop and loop and loop. It affects every character, but you notice it most with poor Leonard because you have to talk to him so much.
I don't know if you've ever played the legend of zelda: ocarina of time, but there's a part in the beginning where you talk to an owl who tells a super long story, and at the end he asks "shall I tell you again?", and the default response is 'yes'. It was infamous at the time, because most players got bored halfway thru and just start clicking ... and would literally click that stupid owl for upward of 10 minutes before realizing they were in a loop. Same problem.
