"Whatever you do, do not travel alone. That way you have memories you both could only ever have known. You'll always have something special with them. Travelling with another person is a gem.
-"What if you'd rather travel and see the world on your own? And just meet people along the way? As you said, you're never truly alone."
"Why's that, Maddy?"
-"Well, what if you're happier alone with oneself? And, sir, you can't leave yourself..."
It didn't exactly rhyme but you catch my drift.
I'd rather travel the world alone because I find it soothing and I've never really been close enough to anyone to want to travel with them.
