Why would you tell him their address (● ̄(エ) ̄●)
never tell someone another person's address, don't tell them your own address, don't tell them THEIR ADRES-
ok but point is, if you/that person who's address is being asked for, don't give it unless you're 1000000000% sure the person taking it is not some weirdo.
and even if they aren't, to your knowledge, you shouldn't give an address when you don't know if that person wants this person asking for it to know.
Dude this has been in the top 5 doujinshi list for as long as I can remember XD
