I'm really happy that you came to visit me.
I really missed you a lot.
I've been missing you like crazy.
I don't understand why you haven't come to visit me.
Lately, I've been quite busy.
Tell me what you've been up to.
I've really been working a lot lately.
I've been pretty busy myself.
So what have you been up to?
I've just been working a lot.
Whatever the reason may be, I'm glad you visited me.
I'm glad I did too.
