Lucifer_in_Disguise,
*custom is a unwritten law... Sounds like the custodian of custom

*which is followed by a set of ppl at a given time...
Are you talking about present day people following custom(past) then your are in contradiction unto your self. If you mean present \"custom\", then there is no such thing. From your statement it looks like custom is transitory (\'at a given time\'). Rationalness transcends temporal limitations of custom.
What I was refering to was the traditional habit(s)/custom(s), some of which may not be applicable to present day society. Thus, what is the rationale for observing them.
