Here's a hint: When someone repeatedly tells you that you make them uncomfortable, that is probably a good time to attempt to be less creepy.

And since you are dense, here's another: When someone doesn't return your calls for weeks, deletes your messages without listening to them, shudders to find your e-mails in their inbox, and doesn't even acknowledge your presence when you show up at their work in hot pants, you should really start to realize that this person does not want to see you or want you to even look in their direction. Ever.
