I am studying the intonation and pronunciation of English. Please care about intonation. Your comments or notes on the intonation would be greatly appreciated.
It may be - at least in some cases - a good practise to not compliment on something that the other person doesn't have much control over. Or something that he or she has been complimented on a thousand times before. Looks and other more superficial stuff are examples of such things.
A compliment that is kinda expected will not be that powerful. And even though your compliment is genuine it may just be lumped together with all those other similar and not so genuine compliments the person has received.
Instead, observe what makes this person tick. What are his/her passions, qualities, interests and proudest achievements? What can you genuinely appreciate about those things?
Now, go out and make someone's day.
