Why cant people just answer the question?

I just had an interesting discussion with my wife. Actually, it turned into her shouting at me.

Here's what happened...

Wife tells me she's trying to watch an <online service> on the TV that we rarely use.
I get a security warning email from the online service that someone tried to logon
I ask wife, "Did you just logon to <online service>?"
Wife replies, "I didn't change anything."
I repeat the question, "Did you just logon to <online service>?"
Wife replies, "I just told you. I didn't change anything!"
I tell wife, "I didn't ask if you changed anything."
Wife replies, yelling, "I didn't change anything!"
I tell wife, "I just got a security alert and I want to make sure it's not a problem."
Wife replies, yelling louder, "I didn't change anything!"
I calmly ask wife, "Did you logon?"
Wife replies, yelling as loud as she can, "I just told you, 3 times! I didn't change anything!"
I ask one last time, "Did you logon?"
Finally, wife yells, "Yes, Yes, Yes. Did you not hear me?"
I tell wife, "That's all I wanted to know. f you had just said Yes..."
Wife is not happy!

My wife now thinks I'm either deaf or an idiot, while I just wish she had simply answered the question I was asking, not saying something related which she thinks answers the question.
