Have you ever talked to someone, and they have that canned interest voice?

“So they donated thousands of dollars to the …”
“Uh huh … wow, that’s great! Yea … uh huh … really? That is really cool …”

Why don’t you just tell me you’re not interested, or you’re too busy instead of feigning interest and wasting my time?

My dad does this all the time, and I do mean all the time. He’s always busy, and when he’s not, he’ll try to be busy. He called and as I was explaining something to him, he did that to me. 5 minutes later after I finished talking to him, I tried to share some good news to my roommate, and she did the exact same thing. What am I, a robot? I wish people would stop wasting my time.
