I have an acquaintance who cannot have a conversation with anyone without "proving" them "wrong" every ten minutes with her phone and Google.
So annoying. Like, who cares what the "correct" recipe is for hummingbird nectar unless you're in the process of making it? It's sugar and water. 2:1, 3:1, 4:1, 1:1 - they don't care.
Keep life simple.
