Překlad - Srbsky-Anglicky - sırpça-hırvatça

The first sentence is rather difficult to translate if you don't put it in the context... For exemple, you might have said something like: 'I miss you'/'Nedostaješ mi'. And the other person could've replied: 'I miss you a lot too.'/'I ti meni puno'.

And by the way, the language is not Croatian, most likely it's Serbian, but these languages are sometimes difficult to differ one from each other to an untrained eye.

I hope this helps,
