Answer

@indubitablee has already found that by

Taking the first letters You get the phrase 'I saw him; he was digging like crazy!'

But I don't think this is the final answer. You see

By taking the 1st of the 1st word, 2nd of the 2nd, etc and repeating at the ';'.

You get:

I saw him; he was digging like crazy!

Which gives

I am Hagey

Which could be a reference to

Gerald Hagey OP confirms that his name is just 'Hagey' and that there is a second part coming to explain.

So I believe that is the final answer.
