What's Your Excuse?

[Seil]

My dad works in the same town as my school, so when he drives into work in the morning, I tag along and don't have to pay bus fare to get some book-learning.

Anyways, today, he was unavailable, so my mum drove me in. It's a soggy, wet, miserable day outside in "Beautiful British Columbia," so I kept my window closed. My mum smokes - quite heavily, in fact - and was content to leave her window open to let the smoke blow out. Well, the inevitable happened and a truck blew past us on the highway at around 90 KM/h, blowing in all of the water on its tires, which caused mum to curse.

"That wouldn't have happened if you had the window closed."

"That wouldn't have happened if this car was designed so that the rain couldn't get in!"

I didn't say anything because I'd probably regret it - but a number of arguments popped into my mind; "It is designed that way - with a window." Anyways, it occurred to me that we all make these excuses to protect our dignity, or to cover our asses. What's your best and/or more recent excuse?
