To some people learning other language is easy but to some it's hard to others they can try.
I have resided in ondo state, okitipupa to be precise for about 5 years now but I can't speak their language, I just hear it small small and can respond when asked questions. But the response is in English. When I tell people I don't hear their language very well, they say it's a lie. If I can't hear my language(igbo) and dialect very well I don't think I can hear another dialect well. It's good you've improved.
