I can relate to the perfume thing.

if their's 1 thing that annoys me, it's people putting on 2 much perfume, then standing right by you giving you a headache
I also relate to cleaning products.. I can't stand in a room where they have been used

for me though, mainly, it's smells that link to memories that bother me and sometimes upset me, or make me react in a diffrent way

lol about the church thing too. that made me smile
