This may be cold comfort, but at the dead level *least*, if you can remove your natural defensiveness from the equation, all of these interactions are a fertile laboratory for learning more about *you*. Hell, you can get too much of anything, but personally, it doesn't sound like wasted time if you approach it from that mindset.
OTOH, man, if *you* don't want to go, don't go.
