what were differences between haris and the narrator reguarding tombs

Harris enjoyed visiting cemeteries and looking at the tombstones. This passtime held no attraction for Jerome (J). 

I objected.  I don’t know whether it is that I am built wrong, but I never did seem to hanker after tombstones myself.  I know that the proper thing to do, when you get to a village or town, is to rush off to the churchyard, and enjoy the graves; but it is a recreation that I always deny myself.  I take no interest in creeping round dim and chilly churches behind wheezy old men, and reading epitaphs.  Not even the sight of a bit of cracked brass let into a stone affords me what I call real happiness.
