Нема на чему Козо! И други пут!

Драго ми је да могу да ти помогнем! :)

Hi, Kozo! There are many possibilities, but I'll write a few examples how a native speaker would write these sentences in Serbian:

1. Надам се да је све у реду са тобом. (I hope everything is fine with you.) 

2. Надам се да је све у реду. (I hope everything is fine.)

3. Надам се да си добро. (I hope you are fine./I hope you are doing well.) 

The first and the third sentences are informal. The second one is neutral.

Formal version of the 1st and the 3rd sentence would be:

1. Надам се да је све у реду са Вама.

2. Надам се да је све у реду.

3. Надам се да сте добро. 

The neutral form stays the same in both cases!

Have fun! :)

Хвала пуно!

Thank you sooo much.

I always deeply appreciate your help.

Have a wonderful early summer day.

Козо
