I was about to write in a mail addressed to an important person "I find hard to believe that I'm speaking to you".
I had a doubt though, so I tried looking for it on a search engine.
I thus found out that it has apparently never been used on the web.
I tried also "I find it hard to believe that I'm speaking to you", same result.
I was rather sure that it was correct, but it seems unlikely after these findings.
Can you confirm me if it's incorrect, and if so why and what alternative might I use?
