Birthdays on Facebook

This past week I celebrated my birthday…both in person with family and friends and virtually on social media…primarily if not exclusively, Facebook.
Now some people might enjoy getting Happy Birthday wishes from people they haven’t spoken to in 20 years. Yet somehow I found it quite creepy. Has this become the extent of our relationship? A lone birthday greeting once a year? Do some people feel obligated to log on to Facebook each day just to check on birthdays and wish them well? Is that the extent of some people’s social media activity?
And yet I got more out of people wishing me happy birthday in person or through a card. Facebook is so fickle.
