With every door that closes, another opens up, That's how the saying goes.
But some closed doors can get open again, That is how doors work, everyone knows.
If you have closed one yourself, it's fine, Better keep it shut.
Just don't give up after one closed door, See the opportunities you got.
Doors sometimes close on accident. Hinges can get broken.
But a push, a request, another try... Who knows what doors will re-open?
