The things once left me have come back.
The one knowing my secrets has never spilled.
The one who is hilarious has been talking to me again.
The one who has once been my best friend is not yet back.

If it's meant to be it'll come back it might hurt but it'll make a U turn for you at some point it's only temporary you'll find someone else or they'll come back!

I'll be waiting best friend I hope you come back.
