Hi Niamh,
The McCarthy family sound like they can offer little Billy a lovely home, and I really hope it works out for him.
I just want to register my interest in case, for any reason, it doesn’t. He’s exactly what I am looking for. A nice, mature, little guy to keep my own little guy company.
Come back to me if for any reason he still needs a home. Otherwise, the very best of luck to you and the McCarthys, and Billie of course 
S.
