Reacting to an Experience (Cause and Reaction): 길래, 기에
A/ V + 길래 shows your reaction (second clause) to an experience/another person’s action. Your reaction is something you decided to do, though it was not necessary/obligatory.
It is common in speech (the literary form is 기에). It sounds most natural when there are two subjects and the first is not you:
