Sometimes, it seems like philosophers define things way different from the way we know and understand them. I do not mean that they say the same things in a Tharooresque manner, leaving us gasping in the dust behind them. No, what I mean is that they seem to have a whole new idea of things that gives this sort of 'We are from Mars, they are from Venus' vibe. Not the 'man' and 'woman' thing but this idea that their thought processes are from a different universe.
Like, Tiru when says this...
Nagudhar poruttandru nattal migudhikkan mersendru idiththar poruttu - Tirukkural
Friendship is not merely to have fun but to reprove when you stray from your path - Loose Translation
Really? Having fun, making you feel happy...is that not the sum and substance of having friends. Isn't that why you gravitate to friends and away from family, especially in your teens? What's the point if friends also start reprimanding you and start giving you advice instead of supporting you, no matter how stupid you are being? If some friend does that, don't you react with, "You are not my dad, so keep that to yourself?" I mean, like, everyone has a role in your personal life and you do not want a friend to be playing your father's role, no?
Well, if you are jumping into a deep dry well, should a friend say 'Don't' or should he take a reel and post it on Insta? When it is starkly dangerous things, it is easier to see the benefit of a 'reprimanding' friend. How about when you want to skip studying the day before an important exam and go to a pub? How about wanting to try narcotics for the first time, say? There are times in your life when you would only listen to a friend and not to parents. There are times when you are intending to do something dangerous and only friends are in a position to know and to try to stop you. AND if all you have are friends with whom you have fun...
Ah, but THAT was Tiru's time. NOW...you merely unfriend the guy who does not agree with everything you say or do; call them trolls and eventually surround yourself only with people with whom you can have fun.
THAT has a name too. Echo Chamber.
