Americans tend to want to be first. You can be an angel on earth by letting someone else ahead of you on line. Another person’s plane might be leaving before yours – you can let them go ahead of you through the security check. Another person may be older, or not as healthy as you – you can give them your spot in the bank line or the package pick-up line at the post office. Helping another person this way makes it easier to practice patience when the line is long and we have to wait.
