Take every stereotype that babyboomers have about millennials, turn them all on their heads, and tweak that collection of thoughts just a bit. The result will be a fairly good description of yourself. You are no attention hog. That said, you may have had negative experiences opening up to people you are close to in the past. That is their fault, not yours. Hopefully at least some of them learn and change their ways. We all have much to learn in life.
