I’m the introvertiest introvert that ever introverted, and I would still welcome more friends – especially ones with more interests in common with me – than I already have.
And I’ve noticed something similar to what you report – maybe not a marked decrease in tendency to get annoyed at stuff, but an increased tendency to put up with boring times because I can make up Pony stories (either featuring actual characters or ones I invent for the situation) in my head. (One character: a unicorn scientist who has Derpy Hooves as a surprisingly non-inept lab tech (the secret? Derpy just needs good lab goggles))
There’s another one – or at least the very brief germ of one that I read – where she was actually Dr. Penelope Hooves, scientist, and her doorplate read DR.P. HOOVES, which some filly interpreted as “Derpy”…..she was fine in the lab with goggles, but on the “outside,” her vision was poor….
Actually, I like “Penelope” as an alternative name for her…
Derpy and the CMCs get lots of fanfic love, perhaps because the writers see them as being unfairly thwarted by this thing called Life — especially poor, flightless, possibly orphaned Scootaloo. Revisionist Scoot stories are everywhere; one came out this past week which revealed that she’s actually a member of a famed Cloudsdale family, slumming it as a character-building exercise.
Nowhere, however, will you find a more positive view of Derpy than in Forest Rain’s song “Great to be Different.”
