Let's say I lived in the US two years ago and I want to mention the fact that I have the experience of living there without mentioning when I did it. Do I say I lived in the US or I've lived in the US? For example:
Person A: I'm going to the US next summer.
Person B: Wow! You'll have quite the experience. I lived there./I've lived there.
If both are possible in the context, what is the difference in meaning?
