We attach to “things” or “situations” with anger (or annoyance) OR ignorance too. That is the true meaning of tanha: “Tanhā – How We Attach Via Greed, Hate, and Ignorance”
One may get annoyed with a fly (some can bite too!) because of its persistence.
– So, one may actually “hate the fly” for being annoying!
People also get annoyed for no apparent reason too. That is due to avijja.
– Someone may just “do not like” another person (a total stranger), for no apparent reason.
– It works the other way too. Some “fall in love” at first sight!
