Idiomatic Expression: Burn the Bridges is a colloquialism for when you just can't be bothered to cross the stream, and would rather just destroy the bridge and be done with it.
Etymology: This phrase is derived from the old saying "burn one's bridges," which means to cut off one's escape routes or connections. In this case, we've added a literal interpretation, where the bridge is not just a metaphorical connection, but an actual, physical structure that's getting torched.
Burn the bridges, burn the pain, and burn the frustration of having to navigate through the water in the first place.
