behind me here um this is the river thames the river that goes through central london and you'll see in the distance what we call a bridge a bridge? a bridge is where you can cross the river we have an expression in english to burn your bridges meaning if you if you burn the bridge or destroy the bridge and you can never go back because once you've crossed that bridge and you burn it or destroy it you can't go back it's impossible so the expression is to burn your bridge or bridges you could say look i burnt my bridge or bridges with my friends meaning that we've had a big argument and we're never going to see each other again it's impossible it's just just not going to happen because we fall them out。
