What does this quote from 'A Separate Peace' mean 'You headed back through the mud you were drenched anybody could see it was time to come in out of the rain'?

Read the passage over and over to yourself. Break down each line and try to get an understand of what it means. When I read over it, I think that it simply means this: Headed back through the mud= went back into the dirty hard times You were drenched= you were covered and had enough Anybody could see it was time to come out of the rain= metephorically this means that everyone saw that it was NOW... to part away from your troubles (the rain). That's what I got from the passage... and I hope it helps. The book is great and even though at times you don't understand things- keep reading. It's an amazing book :]
