So, not responding and directing the attention to the person who asked. Especially useful, if the person asking isn’t even (genuinely) interested, but just asking as a form of greeting. The ones who care might either understand you don’t want to talk about it or will inquire once more.
Hmm… Now that I think about it, that is awfully close to some US American’s way of replying with the exact same question, omitting any kind of reply, concluding the greeting.

Good advice. Unless the trees are trying to kill you (pollen). Many of my friends/colleagues are avoiding trees ;-)
