I'm certain he'll love it
That could be a birthday present!
It would be a good birthday present but I kinda feel like it's better as a no reason present
That's true. I can't wait to hear how much he likes it!
I'm sure you'll be there when he gets it
Well then I guess I’ll be able to hear how much he likes it!
It'd just be weird to give a gift from both of us without you there
Okay well yes that would make sense then
