Lost a Chance A missed opportunity
This morning I looked at saw a foreigner walking down the street. I really wanted to greet / say hello to her but I was too shy. So I lost a chance to make a new foreign friend today. I am very sad.
Thanks for the anecdote. I changed the title to something which sounds common in English to express your situation.
<em>Hi Mustofa,
At first, you "see" someone or something. Then, if you are interested, you "look at" it/them. </em>
<em>"Greet" is good but formal. "Say hello" is informal and probably better in your situation.</em>
<em>We "make a new friend" or "make friends with someone".</em>
<em>Always "today" - never "this day".</em>
<em>Keep up the good work! Kind regards, Michael </em>
