Ah, but I think she was wrong and just not up to the challenge. I have relatively short and stubby fingers. Short stubbies mean work arounds. Barre chords become abbreviated 4-string (sometimes 5-string if I'm lucky) chords. I lose some of the bass intonation but that's why we have a bass player, right? I've been playin' at guitar for right at 40 years. I'm not a big name pro (I play in a church band, do some traditional country/gospel) but I have fun with it.
My current go-to is a Breedlove Acoustic/Electric 12-string; play it at church all the time. My play-at-homes are an Alvarez Jumbo 12-string, an Ovation Custom Legend and a couple of Gibsons. My advice: don't go cheap, get the best you can afford. Also, check out the instrument in person; don't order a $200 guitar online, you will likely be disappointed.
