I have tried in the past to be communicative, bolsterous, cracking jokes, etc.
I found that unless I was sharing this conversation with friends I knew... it went ignored or misunderstood.
I have always figured this was due to the range of ages involved in this game. Being an adult 40+ years of age, my sense of humor may not click with a 12 year old.
As far as it never ending..... Some equate the questing to a series of grocery lists, in which case it never ends. NPC's with thier "Good Job, Thanks.. now go get this...." definately "never" ends.
