What do you do when you are ignored?

Anonymous
If you are being blatantly ignored by someone of the opposite gender, whether dating exclusively, just talking, or even just friends, what is your reaction? This is after trying to address the problem, and them still ignoring you. Then, they contact you like nothing is wrong.

I have been in this situation a few times, and have always wondered what other people did in those.
