“Oh, I guess we're both going the same way, huh?”
When you're leaving work, you ride the elevator down with a coworker. When the doors open, you say "goodbye" to each other, but then you notice that you're both walking in the same direction. You're not sure what to do, since you already said "goodbye". So you say this, awkwardly.
Oh, I guess we're both going the same way, huh?
The phrase "I guess ___" is really useful because it shows that you're expressing a thought that you just came up with. When you use "I guess ___", it sounds like you're responding to the things that you've seen and heard, instead of just expressing a thought that you already had. For example, if you're going somewhere with a group of people, and the other people tell you that their cars are small or dirty, you can say:
I guess we should take my car then.
In the example at top, the speaker says "I guess we're both going the same way" because he didn't know that they were going the same way when he said "goodbye". But now he sees that they are walking in the same direction.
"The same way" means "in the same direction".
When someone ends a sentence with "huh?" it means that they think you're going to agree with what they said:
"Huh" is common when you're making small talk about the weather, or when you're gossiping about someone.
When someone says "___, huh?" you should respond "Yeah!" if you agree with what they said.
