Complicated people for no reason.

How can people be so shameless? Like, the person is super nice, and then they lie to you and are even transphobic. Then you talk to the person, and they say something that you've already made clear isn't true, and they even say you're lying and keep insinuating things. Then you find yourself forced to agree with someone who isn't even your friend, just because the other person suspects something that doesn't even exist. People like that should stop being so complicated for no reason.
