Bruised ego

Last night, Jasper subtley let me know that he was desperate to go outside, by doing his obligatory spaniel spins. Although I'm unsure of exactly how the following events were triggered, I'm pretty certain that it was caused by one of two things: 
1) Jasper had completely forgotten that we’ve had heavy snow,Or2) He was unaware that last night it had finally started to thaw slightly, causing a slippery patch outside the door.

Whichever it was, there was no question of what followed….
Having gained impressive speed from his spaniel spinning, as soon as the door was opened, he launched like a catapult out of the door, immediately slipped, and went stump over ridiculous ears, legs akimbo, with a startled yelp.
Back to uncertainties, I’m afraid my memory is hazy as to whether I laughed heartlessly BEFORE or AFTER checking that he was unhurt. Thankfully the only injury was a bruised ego. Phew!
