Stop in for a cup of coffee

I am depressed and crushed. I was mowing at Andy's house. He had his hammock hanging from the clothesline. Not just a common hammock but one he made himself a few years ago. Special ultra lightweight material and all that for mountain backpacking. It was a turd to sew on the machine and took him weeks and hundreds of dollars to complete. I mowed within a few feet of it and when I came back for the second pass (a few feet farther away) the mower deck picked up one of the strings and wrapped it around the blades thoroughly destroying it. I am so sorry and feel so bad. I don't know how I can make it better. Man, I really screwed this up.
