Insurance and accidental deletion

I went to the travel agent to fill out the insurance form, and worked out that I needed to pay for one more week's insurance, which I did. Before I left, I asked the guy to email me a copy of my itinerary so I can easily pass it on to others who need to know. Unfortunately, when it arrived, I didn't recognise it in my mail checking program, and told the program to delete it. I felt so stupid! I was able to retrieve the first 20 lines, but that wasn't nearly enough, so I humbly emailed the travel agent to ask them to send it to me again.
