How do you say, "I told you so", without sounding cocky?

4 words, that are the verbal smack in the face.

*beware this is going to be a pat my own back post*

I am a very observant person, and maybe its the way I grew up but I keep family and friends close. I am also very picky about my friends. I don’t get attached to people, and I don’t surround myself with people who put themselves in the position to get hurt. It’s one thing where you naturally get hurt, but I can’t stand when you put yourself in the situation where you know nothing good can come from it. So when I tell you how I feel, its not just because I’m ignorant, its because I feel something isn’t right and something bads going to happen. Maybe it’s a sixth sense but I just get a feeling.

So after I tell you to maybe reconsider you’re choices or after you go behind my back, and try to hide things from me because you think I’m ignorant, or I don’t know whats going on, and you end up getting crushed, turned down, backstabbed, dumped, confused, and scarred. I won’t be the one to pick up the pieces, I’m now the bitch. Or at least I would like to be.

I would love to just scream, I told you so… from the rooftops, I would love to just laugh in your faces, or just do victory laps around all of you. I could be that person.

But I’m not.

I don’t want to be that person. I want to just be happy. So how do I say “I told you so” in a resolving way. How do I say, I told you so and I am really not sure how this friendship is going to work because you refused to listen to me, because you didn’t trust me, because you think I’m stupid. I’m not, I was right, I usually am right, and I can’t be friends that lack trust in me. I want to express how I feel, I want to be listened to, and I want to not be taken as a joke.

How can I be right?
