So how's the new job?

Some of my old colleagues or other friends from my old school are curious about about my new job. Here goes a normal conversation:

Ex colleague: "So how's the new job?"
Me: blah blah blah, it's ok,.. blah, blah, blah, I'm fine
Ex colleague: "How's it really?"
Me: I'm fine, blah, blah, blah, ...can't complain
Ex-colleague: And??? (with big, wide, eyes)
Me: (getting puzzled with the look) Huh???
Ex-colleague: "But?"
Me: (aha!!!) No, honestly, I'm happy with the new job. This is how I imagined it to be
Ex colleague: (shows disinterest from now on) Zzzzzzzzzzzzzz
Me: saying to myself - what did i say wrong now this time???!!!%&$&§/!!

I guess people are used to hearing negative things and so on that when you start to talk about good things, it becomes boring. What a shame! At the moment, I don't have that part of the story at work.... of course life is not perfect, there are things you need to learn, get used to, new challenges but that's part of life - nothing special at all.
