'How are you? '
is such a difficult question to answer sometimes.
You just nod, or make some sort of "hmm" sound indicating "ok", and move on to other things.
The grass looks so tiny to us, and so giant to the ant. It is the same with the question - How are you? Innocuous to most of us, and to the rest, an incredibly tough question to answer.
PS: Yes, there is a trigger to this particular episode. And yes, I will come out on the other side. He who has a why to live can always find a how.
