Not a moment too soon, Receiver, for somebody.. This Bearer has been waiting some time for events to unfold, or for the Bearer to reach a particular conclusion - and wishes to mark the culmination of their long-held anticipation.
Receivers sharing both their perspective and their appreciation can concur with Squee, whilst any feeling personally criticised for unwished delay can playfully refute the Bearer’s implicit accusation with Who, me? or Whatever. I'll make it up to you promises recompense, Patience offers a playful reprimand, while My pleasure asserts - however spuriously - any delay was enjoyable to the Receiver.
