Is it normal i am so awkward with people

Are people just too sensitive Or do the things I do sound annoying to you. Asking is someone is sure they know what they are doing

Slamming the door my gf is in staring at her and walking away when she says what> I do this repeatedkly and she gets pissed.
Constantly Critizing someone doing there job because I know it will make them a better person.
Asking a chef if he knows what he is doing when I can't cook anything
Staring with my open and pointing my laser on cellphone at people in the dark.My neighbors' kids constantly make fun of me.
saying huh and making someone repeat themselves a lot because I want to make sure I got it right

Interrupting people when they are trying to answer me

my roommate why she gets pizza from pizza hut because I don't like pizza hut and why she gets pepporoni and mushroom when I hate pepporoni and mushroom..
