I am thankful for the people who saved my life.
Who would you say saved your life?
A few good people saved my life, but to be honest I am more powerful than they are.
It is great to be thankful for people saving your life. It is admirable for others to act in heroic ways, but you shouldn't take away from their accomplishments with your own pride.
I'll forget about them after I'm done bragging about myself.
I don't think you understood what I was saying, as bragging is really just excessive pride and that overshadows the people in your life that saved you and their noble efforts to do so.
