This flexibility is one reason people confuse since or sense so often.

Short Usage Note
The word since comes from Middle English and originally meant “after that time.” Over time, it expanded to include cause-and-effect meaning, which is why it sometimes overlaps with “because” — adding to since or sense confusion.
