Have you ever owned a plant with no particular problems, but got rid of it?
It's very rare for me to completely give away a plant. I gave away Janet Craig Compacta, just so boring, never seemed to grow or change. I don't remember giving away Peperomia obtusifolia, but have had both green and green/white, and doubt I would have killed them. The red edged kind, I just found ugly, and gave away
Red Edge Peperomia (Peperomia tricolor)
I don't think I have ever trashed a healthy plant. It's hard enough to trash a sick plant, but I am about to, with an aptly named 'Dud' red agalonema- can't seem to make it happy.
Anyamanee (Aglaonema 'Dud Unyamanee')
My friend told me her orchid lost all its flowers, so she trashed it because it was 'done.' I about choked.
I would not mind giving away the last of something quite common and easily replaced. Pothos.
