From Dear Prudence (and yes, the advice she gives generally suckes shitte and is grossly het-cis-nuclear-family-infested):
Q. Crazy Sister-in-Law: My sister-in-law has created Facebook personalities for her two dogs and her cat. Her “animals” repeatedly friend request my son and my daughter, who are in their late teens. My kids don’t want to friend their aunt’s pets because when they have, in the past, she floods their walls with unintelligible “animal speak” posts about embarrassing childhood moments. My sister-in-law becomes upset when they won’t accept her friend requests and sends them several unhappy “animal speak” messages a day. My husband thinks our kids should humor his sister, but given her odd behavior, I don’t blame them for not wanting to accept her pets’ friend requests. I even feel the need to intervene on their behalf and explain to my sister-in-law that she’s alienating her niece and her nephew. What say you?
A: Your sister-in-law sounds a little off, so she needs sympathy. However, that should not mean that she’s allowed to harass her relatives. The kids may be tempted to send her an email that says, “Iz no accept puppies and kitty fwends.” But it would be best if your husband—or you if he won’t—just sent her an email explaining the kids limit their friends to their contemporaries and you all would appreciate if her “babies” stopped sending Facebook requests.
