Dear Mr Snail:
I’m sorry I squashed your mother. I didn’t meant it. It was an accident. Please accept my condolences. The garden hasn’t been the same since that terrible day.
Somehow I wish I could make it up to you. I have felt really bad about this incident. I haven’t been the same person since. I know it caused your family great anguish, and I am terribly embarrassed and hurt by my carelessness. In the future, I will watch my step. Please, if I can do anything for you, don’t hesitate to ask.
Though I wish that you and your family would look both ways before crossing the sidewalk.
And avoid salt. It’s a killer.
