Reminder Software

A guy who had forgotten the dates for a number of his friends’ and relatives’ birthdays and anniversaries, decided to compile a list on the computer and have the dates highlighted on screen when the machine was turned on. 
He went to a number of computer stores to find a software program that would do the job but had no luck at the first few. Finally, he found one where the clerk seemed experienced.
“Can you recommend something that will remind me of birthdays and anniversaries?” the guy asked.
“Have you tried a wife?” the clerk responded.
