I just spent the last ten minutes trying to renew my vehicle registration card with him and very nearly started screaming.

"No, wait, now let me read this!"
"Dad, it's the same info we just put in and reviewed."
"I don't fuckin' care, I wanna read it!"

"Is that all the paper that's going through the printer?"
"I didn't know we were printing more out, give me a sec."
"Well, is that all the paper going through?"
"It's all I put in, there's more, just give me a second to get it."
"Geez...when I do stuff with you, I need more time to think!"

"See that address there? I wanted to change that to our physical address."
"We weren't given that option."
"Yes we were, you were fuckin' rushing me."
"No we weren't Dad, that info we changed pertained to our credit card info, not our address, we changed the one but not the other, we couldn't change our address."
"Whatever."

And every time he'd ask me a question and I'd go to answer him, he'd silence me or cut me off and try to figure it out on his own WHEN I KNEW WHAT WE NEEDED TO DO!
