What is the correct sentence?
I didn't do Skype before, with anybody that's why I am little scared 
     Or

Answer

Hi Soniya,

'I haven't used Skype with anyone before, that't why I'm a little scared.'

This would be correct.

You could also say; 'I haven't Skyped with anyone before, that't why I'm a little scared.' 
Skyped is slang for used Skype.

I hope this helps,

Tom
