One woman fooled her Instagram followers, however, she couldn’t fool her sister. Casey Sosnowski posted a picture of herself wearing workout gear and posing with a water bottle with a caption about “nature being the ultimate healer,” the post suggested that she had been out hiking. However, when her sister saw the post she decided to post it to her Twitter page along with a behind-the-scenes shot of Casey having her picture taken in “nature.” “My sister said she was going hiking.....this is our backyard,” Carly captioned the pictures. Casey said she felt “personally attacked” by her sister but it proved to be a hit on Twitter going viral with over 300,000 likes and 40,000 retweets.
