i don't like 'sorry for your loss'
to me it's just a phrase people say by way of etiquette. they don't know what to say so they say that stock phrase. it doesn't bother me though, i know they are trying to be polite and considerate.
i had a rather odd conversation with dd (age 4yrs) when her great grandma died and people were sending me with sympathy cards, as i was next of kin. she couldn't understand why people were saying sorry, seeings as it wasn't their fault. so i said it's a way of people saying they feel sad for us, and it's tradition. i said we should always say thank you when they say sorry to us for our loss, even if it doesn't make sense.
i said on the other thread that it's down to people being different. but that offended the OP, and some other posters, which i suppose goes to prove my point.
