Mike loves his mother. He's showed her how much by writing her a letter a day --- and sending it by snail mail (邮寄信件) --- for the last 30 years. Eleven thousand letters later, the software engineer from Portsmouth, N.H., has no plans to slow down. "You should thank the people you love because one day they might not be there," Mike said in an interview with ABC. His mother, Gloria Britt, is appreciative (感激的), but says, "I could never do that, sit down and write every day." Mike told ABC that he started the practice in 1981. He was 19 years old, and was just starting out in his work in California when he got word that his mother had been in a horribel car accident. He couldn't be by her side, so he wrote to her every day and just never stopped. Mike said he once considered writing to Britt by email, but decided to continue his daily communication in the old-fashioned way. "I have no plans of stopping, ever. The letter-writing will continue on," he said.
