"Hi Nancy, I came over right away to let you know that an errant baseball broke your birdbath in your backyard. It looks like the ball at the top was shattered. Can we go out back and take a look at it right now? (allow response) Yes, I know you loved that birdbath, and I can't tell you how sorry I am for what happened. (out in the backyard now) Oh, Nancy, I can't believe this happened. How can we help make this right? I would love to replace this for you. Can you let me know where you got the birdbath? (allow time to respond) If you want to look on your own, I'd be more than happy to reimburse you. (allow time to respond) Yes, that will work for me. Again, I can't apologize enough for the ball over your fence, and I assure you it won't happen again. You can call me or stop over when you buy the new birdbath, and I'd be happy to help set it up for you."
