Seems like the ones becoming elders in their 20's, have so fully indoctrinated themselves that their entire mannerisms pool around being the quintessential elder. To any normal person they would just seem bizarre.
I know of a young man locally who became an elder. Hes young, a bit funny looking (but married cute even younger hispanic sister from the spanish hall), and not a bad guy. He gives assembly parts appropriate for the new guy so to speak. But he is an absolute bore. No depth. The kind of guy who ends every prayer with
"we leave this meeting in your care and keeping". Other interesting buzz phrases abound. Its like he only speaks in witness idioms.
