Don't post anything I wouldn't want my parents or grandparents to see. They both follow me.

Before you take a picture, ask yourself why you're taking it. Are you sharing a shot of your new yoga outfit to convince friends that you are a calm Zen-like character, rather than a workaholic they know so well? Why do you feel the need to do this, and what does it achieve? Have you shared a picture of someone looking foolish in a bid to boost the social bond you have with your peers? Is it fair to do this, and does it show that you have compassion and consideration for others?
