and thought I had a copy of grief observed by lewis but can't find it...
was reminded recently that grieving is a PROCESS and that the pain of loss can hit you in layers.... so if you are grieving now, remember that!
if you are not grieving now, prepare for that!
The reality is that you can have one thing happen (smell a flower, hear a song, etc) that reminds you of your loved one that you've lost and BOOM! it is back, the grief has found a new layer
amazon has lewis' GRIEF OBSERVED and you can also preview it at google print:
