3. They Don't Get Any Of Your Jokes Or References
With your friends and family your jokes go down a storm and you pride yourself as something of a comic. At work, you're just met with a blank stare as you realise they were probably just a twinkle in their father's eye when your favourite comedian was on the stage. Try quoting anything that wasn't on TV after 2005 and you just get polite laughs as you know they're thinking 'what the hell are they talking about?' And YOU'RE the one who is mocked for knowing who Elvis was.
