Another thought I had, was something I often heard when I was young:

"Don't pick the flowers!"

As a child I would be sent on a guilt trip for trying to experience love more deeply, by experiencing the beauty of a flower or by giving it to someone else.

The reason for owners not wanting flowers picked is legitimate, but my subconscious could have taken it the wrong way, and a false learning integrated.

I now may have a fear of choosing flowers at a flower shop for others because "I can't pick the flowers"

Funny how the subconscious works. Every child has genius, a few escape being "degeniused".
