Frustration

My mother is never happy with the first answer you give her. NEVER!
Example:
Mom: Is it hot at work? FYI there is no AC at my work.
Me: no
Mom: really?
Me: well it hasn't been hot so it's not hot in the office
Mom: your dad says it's hot. He's brought in a fan, but it was too noisy and he returned it.
Me: I'm not hot and there are ceiling fans.
Mom: looks at me unbelievingly
Me: there's almost one per cube. There are 6 in my area.
Mom: omg isn't it windy then?!?!
Me: no, I turn mine down...
Me: ok I'm leaving for work...
