This carries on a little bit from my last post.
Because the key is clichés.
I was watching a football programme the other day on tv, and the interviewer said “please don’t give us the cliché answer”. It’s exactly like that when you speak a foreign language. You’re supposed to give cliché answers like (to take an extreme example): “oh la la”. And people do.
Plus it helps get you in the mindset. So the mental block to pass is to get into the mindset, and make yourself use the clichés, whether you like the language or not. You will (hopefully) find yourself liking the language once you’ve got past this stage and you start using clichés… it will help your learning no end.
