What does it mean when a woman calls you a nickname?

[LinkxPeach]

Yesterday, I went to talk to a female friend, and she gave me a nickname.

I'll agree with the first 2, She possibly likes you , but can't remember you name,

I personally, am terrible with names.

That’s a sign of affection.

It means she can't remember your real name
