Luokse, luona, luota

They are used to express the construction "to/at/from someone" or "to/at/from someone's place". For example:

Olin eilen kaverini luona. I was yesterday at my friend's (place).
Tule huomenna luokseni. Come to me / to my place tomorrow.

One particularity in usage of these constructions is that it is incorrect to use it for the same person as the subject. The following examples are incorrect:

Palaan takaisin luokseni illalla. I will return to my place / home in the evening.
Milloin lähditte luotanne? When did you leave from your place / home?
