Would you please correct my sentense?
You do not know how much I have wanted to see you.
I am so glad that you decided to come to Istanbul.
Can I say to a person who is 20 years old:
(you really grew up. you become such a gentleman). or you are really handsome? What else can I say to him when I meet him for the first time? How can I compliment him? I only see him in the picture when he was little.
I always keep his picture in front of my mirror in my room.
At the end of the conversation: can I say I will hang out with you or come over to my place. I hope you enjoy the time here ( because he is a visitor to Istanbul) I will see you soon.
