Why are my parents so stressed over nothing?

I apologize if many of my questions are usually about my parents but bear with me, I live in a dysfunctional family

Anyways, my family always works like this…you have to ask for the vehicle before taking it to work…you have to say goodbye…while that may seem simple enough, it isn’t…trust me

Asking for the vehicle is the most awkward thing in the world…I don’t know why but it is…and if I don’t say goodbye to them before I go to work, it’s like the end of the world or something.

Tonight I was told I had to get ready for work for 5:30 by mom. But she had to get all tense and say “You gotta go you gotta go get up get up!!”…I started getting dressed for 5:15, and got in the car for 5:20pm and just left. I just wanted to get out of there since she was making me stressed out…I was irritable for the first hour of my shift then I calmed down…

Now they have this long talk with me how they don’t like my attitude…long story short I’ve been spending time with my new girlfriend Kim and I haven’t been very punctual coming home on time. I’m sorry if love somehow hurts my parents the way it does…oh apparently I’m rude too…I just don’t wanna deal with useless anger and stress…I’ve dealt with it for 20 friggin’ years thank you very much…make that 21 on my birthday

All I can say is thank God I’m going to be driving my new Mazda truck soon and I won’t have to deal with borrowing the car anymore but why in the world do my parents get stressed over the dumbest things like this…It’s not worth it, they’ll pull ulcers over nothing before they turn 55…
