My dad Works in IT supporting an enterprise class Phone system and work management network so Most adults we know contact my dad for support, But some of my friends despite being PC Gamers are so dense sometimes, The worst thing is That many of my friends don't realize that allot of the "Download Now!" buttons on download pages are not the proper download and are just an add. and they also don't know that install wizards are there for a reason and you shouldn't just spam next till its done so they end up with a bunch of addons tool bars and ad-ware that they "never downloaded."
Another thing is when my friend in 8th grade was Convinced he knew so much more about computers than me (At the time I didn't know much but I Knew as much if not more than him.) he was always talking about building his own custom pc but never got the money so instead just upgraded the old desktop he used to a gtx 650 or something like that. and at the time it was good enough. But low and behold now, about three years later i built my custom pc And he gave in to the fact that I knew more than he did.
