In friends, the drama, I heard this sentences. but I couldn't understand what 'would' means.
I can't believe you would have a 30 year old daugther! And you! I can't believe you would have a tux that's 30 years old!
Having a 30 year old daugther and tux was already true. Then, why did he use 'would' in this sentence? Is this like meaning of 'might'?
