What do you do when you can’t think of clever captions to post online? Simple, you try to impress people with old proverbs and quotes instead. This OP clearly thought he was being smart when he posted an old African proverb that read “The youth can walk faster but the elders know the road.”
What it means is that older people have more knowledge because of their life experience and can therefore guide young folks down the right path. Of course, someone had to take it literally and make it a joke by saying that the youth these days have Google Maps. Hilarious!
