Gee, I wonder what the reason was.

Redditor Shade1453's Aunt Julie may not understand much about the Internet—she printed out and mailed Grumpy Cat memes to her niece and nephew, after all—but she does understand one key thing. The best way to subtly take a dig at someone is to send them a link (or in this case, a printout) and say, "This reminded me of you."

Whether it's an article about entitled millennials, a BuzzFeed list called "10 Things Everyone Who Disrespects Their Parents Knows," or simply an angry cat who can't get along with others, all you need to do is tag someone in a public post to send a direct message (so to speak).
