Hoarding sub-message in "Trader's Exchange" s4e22

[IlikeBoris 13]

Spoiler light, I hope.  Twilight Sparkle wants to get rid of some books that she doesn't have room for, and Pinkie helps to convince her not to get rid of them.

 

I'm borderline for hoarding, technically a clutter-bug with a few health-code slippages, so I'm sensitive to clutter issues.  One of the problem areas for overabundance is books that are kept for sentimental reasons rather than actually wanting to read them again.

 

I can't help but feel that Pinkie did a bad thing, damaging a healthy attitude towards letting things pass out of your life.
