I waited in vain for a response.
Thanks to that, I was stood up for about an hour at a desolate station.
Could you please tell him tomorrow’s conference has been cancelled so he won’t feel like he’s been stood up?
With 待ち you know you're waiting, but what's a ぼうけ? Turns out it's the long version of ボケ which means idiot. Basically, in this case you're a waiting idiot. Why? because you were stood up.
The reading for 待ち comes right from 待つ. You know the drill by now.
