Hi Tony,

Great job on using the expressions we discussed from our previous lesson. It only proves that you're attentive and willingly practice all of those which will help you to get use to it and improve your sentences. I changed some words to be more approriate to the sentence so it would be clearer. We could also discuss this if you have any questions. Nevertheless, I feel delighted that you're not hesitant to use these expressions and new words. Keep it going!
