Beaten to it again!!

You beat me to it Deli!! I could've managed that one!

Haklısınız!

Deli-I'm happy to have you as my teacher!

Is it-bana dargın etme lutfen?

Did you miss out the please don't be angry with me part?

Does't başka birşey istemiyorum mean I don't want anything else ?

I think it's either depending on context and I've seen it used more for worrying than wondering on this site but you could be right in this case !You see merak etme often which is don't worry.

You're welcome.

Bir şey değil.
