After an interesting conversation — complimenting someone's mind is the most sophisticated and durable form of Italian flirtation.
'Mi piace il modo in cui' = I like the way (in which). 'Pensi' = you think (second person singular of 'pensare'). Complimenting how someone thinks — not what they think — is a specific and unusual observation that shows you pay close attention.
Hai una mente brillante.
You have a brilliant mind.
Direct intellectual compliment — 'brillante' is used in Italian for sharp, clever minds

You speak in a way that makes you want to listen more.

Ogni cosa che dici mi fa riflettere.
Everything you say makes me think.
You have intellectual impact on them — a powerful compliment
