You know, he has that foot in mouth disease in canon, like in SWM where he goes on about how awesome the full moon would be and Remus just mutters about how only Sirius would think that. It was thoughtless and self-centered and sometimes Sirius is like that.

And oh, man, this is me too! I'm far more likely to pop out with something thoughtless at times, especially when I'm excited, than I am to carefully think my words through.

Thank you for giving this a read, you are a doll.
