Your parents are not on this earth to cater to your life. They can accept a wedding invite and yes they can make you miserable by 25 Years 1996-2021 Space Jam signature shirt you miss your BMX event. In the grand scheme of things why is this such a big deal to you? You’ve posted this before or it just popped back up on my requests, idk and I didn’t want to reply but here it goes.
