Sure! There are some tips that might help.  You should make it clear to the person that you're not happy with their decision, and explain why.  Also, if you're planning to go out with them, make sure you check that they're going to be willing to pick you up or meet you there.  If you're planning to bring up the topic directly, you should be prepared to hear what their perspective is.  Remember to try to resolve conflict by trying to understand their point of view, and to talk to them about what you're feeling.
