I apologize for just about everything, even if it clearly isn't my fault or something I have no control over. I also apologize to inanimate objects when I bump into them or something. 

I broke your grandmothers vase? Sorry. 

To hot outside for your liking? Sorry. 

It's literally such a bad habit for me my friends used to call me their 'Little Canadian.'

[s] No offense towards any Canadians here, of course. [/s]
