"My daughter has been acting strange the past few months," wrote a parent n Yahoo Answers recently. "She's always on this website called Tumbler. ... Sometimes she says strange things like "my feels" or "my cries." ... Yesterday she was crying because of shipping. Is shipping some kind of drug term or a cult? I don't want my daughter involved in negative things like this."
Don't worry, was the general consensus of respondents to the worried father. Your daughter's not in a cult — she's just in fandom.
