Birthday party - Who are the gifts for? Who gets the attaboys and congratulations? The person whose birthday it is right? Witnesses say birthdays are pagan and wrong.
Anniversary party - Who are the gifts for? Who gets the attaboys and congratulation? The individuals who got married a certain number of years ago - Witnesses say this is acceptable.
Bridal showers - Who are the gifts for? Who gets the attaboys and congratulations? The individual(s) getting married - Witnesses say this is acceptable.
Baby showers - Who are the gifts for? Who gets the attaboys and congratulations? The gifts are for the ones having a child to use with/for the child - Witnesses say this is acceptable.
Wedding receptions - Who are the gifts for? Who gets the attaboys and congratulations? the gifts are for the newly married couple (the gifts are not for the 'marriage arrangement') - Witnesses say this is acceptable.
If you feel that giving honor to a person or being other than Jehovah is wrong then actually live by those ideals. Don't pick and choose what is acceptable and what is not.
My question to my witness friends is this: Why are you constantly training your conscience if you aren't allowed to use it? Ooops, except when you're told it is ok to use it. :)
