['Hi.  So I recently found out I was selected to go to a cool work conference out of town.  Only 2 other people in the whole company was invited to go on the work trip!', 'That sounds like a good opportunity for you!', 'It really is.  I was very honored when I found out about it!']
That is great.  It will probably be good to get out of town for a bit too.
I recently was selected to go to a pretty awesome conference out of town to represent my company.  I was one of only 3 people selected and I did not expect it to happen.
