The Last Word

The LW realizes its mistake and has promptly returned to me.

And just as promptly left.

To once again have a good time at my side, the party is in full swing now.

It will need to continue minus the last word.

The LW invites you rather to join us.

I'll accept the last words invitation to have it.

The LW feels lonley without me.

You must mean the other way around.

No he actually meant it is lonely without my company hence it's return.

Yes, it's return to me.
