Susana, I know what you mean. Starting to be more openly appreciative and complimentary was/is a bit weird for me. Sometimes it just feels/felt a bit false. The more I do it the easier it gets
for what its worth i think the example you gave was good - probably because you really meant it
so the only tip i really have is keep doing it and be honest, over time it will become more natural.
