Hello!
Here is the following situation:
The question: Does the way we wear our clothes makes us the person we are?
The answer: The clothes don't make the man. You'll often find that most people think along the same lines and are interested in the same things regardless of how they dress.
Can I say 'think in the same way' instead of 'think along the same lines'?
Thank you very much!
Yes.
It's 'in a similar way' rather than 'on the same way', but there is no great difference here.
Context is always important; labelling is rarely important.
