I got two very different reactions when I shared my travel plans with the family members I'm going to visit.
Family member #1: "Are you sure? You'll be so tired when you get here. Do want some money so you could fly instead? The trains are usually late, you know. Are you sure you want to do that?"
Family member #2: "What a fantastic idea! You are going to have such an adventure. The kids will love it! I love travelling by train."
I bet you could form judgements about the speakers based just on the above reactions. And you'd probably be right. This is why dialogue is so critical in writing... it reveals SO much without having to tell the reader specifically.
