For me it correlates so yes. I’m not saying one is necessarily caused by the other.

Conversely, I set up birthday reminders for the people I care about.

If they’re close friends and family I definitely expect them to remember. It’s a good indicator of who I can trust in my life as well, those who usually remember just also happen to be on the trustworthy list.

In essence, this quote is true.

Applied to reality though, in our day and age your results may vary. It is completely possible to travel and learn nothing that would open people’s minds especially when the traveling keeps itself within tourist zones and resorts designed to just give you a change of landscape and an illusion of cultural flavor.

You need to purposefully step away from that sort of thing and actually engage with the culture to get the benefits of the quote.
