EDITOR#11:
From the tone of your question, either you are truly curious to know the source of my knowledge or you already know the source and are a bit of a skeptic. It’s alright, we all are skeptics in some way.
Seeing that you sign off as an enthusiast of wild animal sightings, let’s put it metaphorically: my knowledge is a wild animal itself. I search for the answers just as a thirsty wildebeest searches for the nearest watering hole with the least amount of lions. In other words, I give advice that is helpful but not super risky to tell to an anon who may or may not be easily offended.
By saying my knowledge is a wild animal I’m not saying that it is unruly and I pull advice out of thin air. I think just as you would think. For example, it would not make sense to give friendship advice to someone who asked a question about completing college applications, just like it wouldn’t make sense to pull out my binoculars and expect to see crocodiles in the Saharan Desert.
