['Recently I knew that my friends were going on a trip and I really wanted to go.', "Was there any reason you couldn't go? Did they not invite you?", "At first I thought that there wasn't enough room, but then there was!"]
That's wonderful! I hope you had or have a great time!
I knew that some of friends were going on a trip and it was unlikely that I'd get to go. Surprisingly I got to go so I was really happy.
