How many games? I've played in three, including this one. Why do you ask?
I just wanted to know why you're telling everyone that I'm town when the only possible way you know that is if you're scum, seeing as how you've had three games of experience. There's not really a reason you should ever say that, and I'll tell you why:
Let's think of 4 possible situations, 1 of which is currently impossible (Well, 2 technically, but 1 through game mechanics), but since this is all rhetoric, it doesn't matter.
Situation 1: We're both town.
This is likely what it is, but this isn't always going to happen. In this situation, yes, you're lucky. Both players are town and you believe the other to be as such. It still stops others from being suspicious, even if you're right.
Situation 2: You're scum and I'm town.
This situation makes it so you know that the other is town simply because you're scum. This is what is usually called "buddying," and keeps people from suspecting you because you don't suspect them. It's a tougher scumtell to find, but it still is one.
Situation 3: I'm scum and you're town.
This is, by far, the worst situation that you could stumble upon. Not only do you believe one player is town, you've basically said it in front of everyone else. This could stop other people from looking at all suspects, instead of being suspicious of everyone. See Beginner Mafia 1 for reasons why not to do this.
Situation 4: We're both scum.
This situation is meant to cause one of the two situations above it, by either making others believe one of the two are scum, or by saying it was a mistake when it comes up wrong.
It's just a bad idea. If you're wrong, then it screws everyone up (Like when I said Vector was town... after trying to lynch him for 3 Days). If you're right, then alright. You just want to remain cautious of everyone. Just because it may look like someone is town, doesn't mean they're town. That's what the mafia want you to think about themselves. That's why it's called mafia.
Just avoid it in the future. Say something more along the lines of, "I believe you to be town" unless you know for a fact (Cop) and even then, be careful (Godfather, Insanity, Naive...).
Now, who do you believe to be town besides me? I'd like to know.
