At the end, can be used to refer to the end of anything. It is a literal phrase.Originally Posted by ExK
'In the end" is an idiom. It is used to mean, "after everything happened".
I would use "on your left" if you were standing next to the building and it was on your left side. "I would use "to your left" if I were giving you directions" as in "take the first road to your left". They are not greatly different, however.
