We have a few sayings in our workplace, one of them is you never say things like 'to be honest', or 'I'm not gonna lie', or 'to tell the truth', this implies you were lying all the other times you didn't give your disclaimer. Why is it that now you feel like you aren't going to lie? Isn't that one of the assumed parts of having a verbal interaction with someone, that you are going to speak the truth. 

The world is your stage, live every moment like its opening night. Mistakes will be made, but the excitement from the adrenaline will push you through. 

The euphemism I hate the most is when someone comes up to you and asks you a question, and do you want to know what the question is? Take a quess, nevermind, its dumb, I'll spare you. This is the question they ask me, 'Can I ask you a question?' 'Do you mind if I ask you a question?' Can I ask you something? ... I'm short on answers as it is, and you just wasted one.
