Is this true for any of you guys??

One time I was picking up my brother and I had called him before to let him know I was coming and when I got there he didn't answer his phone and so I went to knock on the door and no one answered for about half an hour

Or they think you are disrespecting them and it's a secret fuck you that you are trying to get across to them

Its absolutly completely true

That's what I think when my parents don't pick up

You forgot a "you obviously must be having sex" section

If the green part was"you're ignoring ne on purpose" then it would totally be 100 percent true
