Daisyanswerdo There are no words, sending you a hug.
Fortunately, we all understand the euphemisms and people should feel free to use whatever is suitable at the time. We need to be guided by the bereaved though or risk upsetting or even offending them.
Totally agree with TwiceAsNice that we must be very clear with children and also careful that things aren't 'lost in translation', as it were.
The pet scenario works well and prepares children for life. My granddaughter, aged 6, insisted that the long dead and buried goldfish was exhumed and went with them when they moved house. Needless to say, Daddy 're-buried' (cough, cough) the fish whilst granddaughter was asleep the first night in the new house and she put the original little painted stone on the 'new grave' in the morning. Well, sometimes a white lie never hurts.
