Oh gods, Bill wanted to laugh, Charlie could see it on his brother's face. He was going to laugh at Callum and then Charlie would have to punch him or something and gods this was not the way these sort of things were supposed to go. Charlie knew that much about traditional weddings.
Amazingly though, Bill managed not to laugh though his response was not exactly the sort of thing he had considered to be the kind of thing that Bill could have said - though it wasn't the worst thing he could have said either.
"Well thank you for your congratulations, we appreciate it really - but Callum is asking for your blessing, not your congratulations. We're trying to do this right, and a blessing from the family is part of that. And I know in our family, traditions don't always hold a lot of water for us, but can you just ... take this seriously? For me please."
