Here's what they said:
1. "My nan doesn't think women should drink out of bottles. She will insist that if you are a woman with a bottle of beer/soft drink, that it goes into a glass. Just women though. It isn't ladylike apparently!"
2. "My dad gets baffled and downright pissed when he hears of women traveling without their husbands. 'Girls' trip? And what is the husband supposed to do while you're gone? Just be at home? Insanity.'"
4. "The older adults in my family hold the belief that children and very young adults don’t have real feelings, basically. If you’re under the age of 25, you NEVER know what you’re talking about, so shut up and let the grown-ups talk."
5. "That you should work 9 to 5 at the same job for 40 years to retire and get that gold watch and a pension."
6. "They think by the time you're 30, you should own a house, two cars, and be married with two children."
7. "That everyone going to college/university must be extremely smart and other professions are for the not-so-privileged ones."
8. "That saying, 'No problem,’ or something in a similar vein is somehow ruder than saying, ‘You’re welcome.' This is something I’ve had elderly family members mention a few times, and I genuinely do not understand it."
12. "I think older generations are way out of step with tattoo acceptance. I was raised that it was just for sailors and prisoners."
13. "When they say, 'Just go into that business and ask to speak to the manager about their job openings. He will be so impressed by your initiative, he will probably hire you on the spot.' No, that's not how the world works now."
15. "When they think you shouldn't be able to move in with a significant other unless you are married."
16. "That online friends aren’t 'real' friends. My grandparents and I always disagree with this."
Do YOU have any examples of outdated millennial social constructs? I'd love to hear them in the comments!
