You had me puzzzled there optom with your word: observational !!
And, it just come to my mind that observing can be humour or fun !
Somehow, even, observing flowers can be like a sense of humour for me:
like when I looked at daffodils in bloom yesterday; one had it's head bent low, while another bloom was upright and proud like ! Does this make sense ??
Somehow ?
Au revoir,
hugs! And after cleaning the yard, I visited one of our good neighbours, and I noted that her sense of humour in life was great, as she said that instead of selling her second lot, she still had in her 80's plus years of life ANOTHER year to add plants to it !! And, she likes the small baby or adolescent daffodils that are there among the big adult ones !! Life goes on !!
