Again, just from a common-sense standpoint, I can tell you that from my perspective, at least, I won't print off an attachment unless I know what's in it. In other words, we receive many, many e-mails, many containing attachments, on a daily basis. I don't print off every e-mail I receive. I certainly don't print off every attachment I receive unless I know what's in the attachment and that it's worthy information, important information to me. Then I print it off, because I want a hard copy.
You say that you printed off the attachment but didn't know what was in it. You just went ahead and printed it off. I find that not only odd, but quite frankly a little unbelievable.
