1. Friends who constantly post about their relationship
The internet is not a place for happiness. Happiness belongs in the real world. The internet is the place where misery finds its company. If you’re constantly posting about how happy your relationship is, pretty much everyone knows that it’s not all that happy.
2. Friends who constantly post about their babies
Look: we all love kids. But by definition, a miracle is something that doesn’t happen frequently. It’s a rare an unexplainable event. UNICEF estimates that 353,000 kids are born every day, and birth is totally explainable by science. So your child is not a miracle, unless you want you set your standard for “miracle” so low that that socks and intestinal bacteria count as miracles as well. We’re happy you have a kid, but please: give your posts some variety.
