As-Salaamu 'Alaykum,
I think it'll be better if we speak different languages.
Less arguments.

Besides that, I think we can pick up each others languages eventually allowing us to understand one another so thats always good but that would mean we cant have kids right away, unless we use sign language.

Wow, that would be a cool union.
Ermm, now Im actually interested in marrying someone who doesnt speak my language.
Was-Salaamu 'Alaykum Wa Rahmatullaah
