"When I was in....."
Everyone's been that person or known someone who's that person. You return from an epic journey across the world and want to tell everyone about it. Naturally. You've seen incredible things and met amazing people that your family and friends haven't, and all you wan't to do is share it with them.
Stop right there.
When I returned home from my first long term trip to Europe (Germany), I could feel my friends and family getting annoyed with them as I gushed about everything. "BUT THE MAYO THERE IS SO GOOD! AND THEY EAT IT WITH FRIES!!" "IN GERMANY THE CLUBS ARE INSANE!!!!!!" "THEY'RE SO FRIENDLY THEY PUT CHICAGOANS TO SHAME!!!!!!!!!" I wailed.
Cute. Real cute. I was pumped about the mayo. (It is legit).
I started to hate myself as these words poured out of my mouth, but I couldn't help it. I wanted everyone to know what I had experienced so they would want to experience it too.
But that's not realistic. Over my travels, I've learned to develop my own "don't ask don't tell policy."
I'll tell someone if they ask me about it. Otherwise, I keep my mouth shut. Because usually, they don't want to know about the museums and sights you've seen, unless they're really interested. Telling them about the people you've met and the adventures you've been on is a little more likely, but still.
It's hard not to sound arrogant when someone asks "what's your favorite place you've ever been" and you respond "I don't know! There's just so many beautiful places!" Try to stay humble, and be humble. Don't brag, but inform. Note what you have observed but don't do it with extravagance.
It's a difficult balance, but it'll make your family and friends not hate you in the first few weeks after returning home.
