I've been a reader of this comic for... wow, like, 20 years or something.  It started out as fairly generic drawings and humor, but with some really poignant, emotionally vulnerable storylines that were strong enough to pull me along for the entire ride. This panel is an example of one of the "obviously not funny, why is this in a comic strip" moments where the writer's personal journey bleeds through into some seriously empathetic, emotionally raw moments, and it's really quite beautiful. I won't spoil anything in the series, as I recommend reading it from the beginning, but suffice it to say, pack a lunch.  There's a lot of content there - most of it highly unquestionable ;)
