If there were some things that were difficult, others were nearly impossible. Such as refraining from laughing right now. Forcing himself to take a sip of beer, he tried to push back the urge to laugh, because while he wanted nothing more than to laugh, he could see (and clearly hear) how nervous Callum was and he was sure laughing in his face was not hte correct response.
With a mantra of don't laugh, don't laugh, don't laugh repeated in his head he took long deep breaths while biting his tongue and not asking Charlie if he was the blushing bride and if they could throw that hen-party for him now.
What felt like an eternity later (though it was a matter of seconds, the time it took to swallow and put the beer down on the table again) Bill trusted himself to open his mouth.
"Congratulations?" he said, looking between the two of them, and dammit Charlie owed him big time for keeping a straight face. "I'm not sure what the supposedly right answer is here, but congratulations pretty much covers my thoughts on this. Other than taht? Welcome to the family and brace yourself for the insanity?"
