What's going on with me??? Why was it a problem for me to communicate with...

I said only "Thank you for coming" to a very interesting young man, who works in Baku. It seemed to me that he wanted to start a conversation, but he had a lack of confidence at that moment.
I wrote only the sentence in the very beginning in my blog and went to the assistants and began to talk to them.
I asked about the difference between Peace Corp's Volunteers and workong as assistants in Brilight...
They are working in Baku.
Then 5 minutes later I met with Amanda... she is the first American I spoke to... (She asked me something about e-mail). And at last I met with her.
I am so glad :) she is so sweet!!!
Before the programme she worked as a journalist and she is from New York city.
I told about DVD about N.Y. I had watched yesterday. Next phrase made me extremely happy!!
- Whom do you want to be after graduation?
- I don't know exactly. I am only a first-year student. I'm studying Philology, here in Kyiv-Mohyla Academy, so I have to study for 6 years; and I'm sure my priorities will change.
- Have you ever been to an English-speaking country?
- No...
- Your English is so good.
- Thank you; but I have to improve it all the time. I don't have a possibility to practice it as often as I want.
- Oh, I understand...
And so on. I am so happy. Why didn't I talk to her earlier?
But still Amanda, a very positive and bright person, made me feel better, feeling happy.
Our talk was very interesting. I'd like to keep in touch with her, but I'm sure to take contact information after 5-minute talk wouldn't be polite...))
