Look everyone in the eyebrows instead of eye contact. Always call people buddy or guy. Then end your sentences with "eh?" as it is polite and invites further comment. I hope that helps you talk to people buddy and be considered normal,eh?
Whatever floats your boat guy.
That sounds like one of those self-help book titles: How To Talk To People And Be Normal (Written by Oprah Winfrey and Illustrated by Thich Nhat Hanh)
So you know there is a normal? How? By the way people glance, or turn silent? <br />
There are social standards, one can learn them like a dog can learn. You check out the group and participate as best you can. <br />
And you try and find a few who you have some things in common with, so that the stresses of being 'normal' are not taking over.
Act that way. Realize you're really not the center of attention. People are much to busy thinking about themselves.
Focus on them.
It's not odd to be bored among humans.
Don't mention the ****
What part of your speech, conversation or behaviour is not normal?
That is pretty broad. I'd suggest NLP "How to make friends in 90 seconds or less" as a good broad book on how to interact successfully and somewhat 'normally'. It covers things like greetings, finding common ground, attitudes and establishing rapport. However if your voice is abnormal you may need to practice or get voice training first.
If you are a female you don't need a manly voice!
That was me too. Don't worry about shy and insecure. Talk to people you don't know, then it doesn't matter if they think you are a bit odd, they'll forget you before you talk to them again, but you might make friends, and at least you will practice.
Nothing ventured, nothing gained.
It is one of those areas that you can fake it until you make it.
BTW: you may have things in common with people not your age..... otherwise, eventually, you will be a standout in your age group and may even be popular because of it (I've developed my stability, knowledge, wisdom, but I'm still not popular).
