Severus Snape

He hates being pitied. To befriend him, you need to be patient and not be offended by his rudeness. You need to be quiet, smart, reliable, and unobtrusive.

Don't mock him, don't pity him, don't compare him to others, and don't touch Lily. Unless you're James Potter or the Marauders, you have a chance of just neutral communication. He hates it. If you want to be his friend, be prepared for him to test you for years.

When he received pity or compliments, he always thought, “Do I deserve this?” And this is always the case when a person becomes close to him.
