Why am I here?

If I tell you that I will look into X, Y, and Z...and you've worked with me before and know that I generally do what I say...then why would you look into X, Y, and Z yourself?

If we're on a conference call and you start talking about X, Y, and Z, and I say I've looked into that, why would you ignore me? Why would you start playing around with X, Y, and Z yourself?

Why would you interrupt me when I start to tell you my findings of X, Y, and Z? You made me want to bang the phone on the table and ask, "Is this thing on?"

Jackass.
