Are monks expected to accept life lessons from (time spent with) the laity?

In general, the monks are expected to preach the *Dhamma* and the laity should listen. But "behind the scenes", so to say, should monks really be learning from at least some situations they run into without the attitude they know better or that they already have the full truth? I think I might know the answer, but I am looking for any sutta/tipitaka references or analyses. Also, additional/complementary *mahāyāna* point of views and references are welcome.
