It’s definitely a sign of the times! The biggest way to tell if a new relationship is serious or not is…whether you know the other person’s last name. The reason why this is considered ‘serious’ is because you’re mostly meeting people on dating apps, where you only see their first name or username. Or if you ARE meeting someone in real life, you might just put them in your phone with their first name and the place you met, like “Steve Safeway” or “Tammy Yoga.” (Photo: The Local Norway)
