Stop in for a cup of coffee

Unfortunately some things are hard to 'clearly' define. Sometimes we have to use our judgement, which is by definition, subjective.

even IF one could argue its not politics, the conversation will almost certainly go there anyway.
That's a slippery slope and really no reason for it. When it goes there, then act.
