Would you go visit someone at their home if they told you they had a ghost who resides there too?

Depends.  Is it a friendly ghost?

(FWIW, I formerly didn't believe in ghosts.  After renting a house for five years which was clearly 'haunted,' my views have changed considerably.  There's nothing like empirical data to change a person's mind.)

No, but to avoid the person not the ghost. 

Bigot.  :-D

depends on the ghost of who

Just because it is friendly with them doesn't mean it will be friendly with you. :)

Yup.

Yes

Excellent point. :-)

Nope

Yes, that would be interesting.
