The phrase ‘same difference’ is often used colloquially to express that two things being compared are essentially equivalent, even if they might seem different at first glance.
For example, if someone says, ‘I prefer to take the bus instead of the train,’ and another person replies, ‘It’s the same difference; you’re still not driving,’ they’re implying that taking public transport is similar in outcome, even if the modes of transport are different.
This expression can sometimes carry a hint of sarcasm or dismissiveness, suggesting that the distinctions being made are trivial and not worth considering in the larger context. Overall, it’s a casual way to downplay perceived differences and highlight an underlying similarity.
