@ mshades - Thanks soooo much this is perfect!
@ Scyllacat - I will have to mention the milk example, he loves idiomatic expressions.
@ Anita- No worries, I will definitely use what you said above, though my student has a high level of English, it was more a clarification than anything because he is giving a speech soon and wants it to be perfect...well as perfect as possible with his Murcian accent.
Thanks again to all! I will be sure to use all of these on Friday.
