In some cases like my great grandfather, I suspect he actually enjoyed the conversation because he was bored. Even though we went to his house nearly every day, there&#x27;s still a lot of hours in the day.<p>He didn&#x27;t get scammed over the phone but he probably had his driveway re-sealed 4-5 times a year. We would chase them away but they knew they could get him when there was nobody else around. Sickening people who do this.<p>It seemed possible that he knew his driveway didn&#x27;t need sealed, but he would sit outside and chat with them for the 3-4 hours it took to do the job.
