I think a lot of us laugh because if we didn't we would cry and for some reason, that never seemed to be an option. Old tapes keep us sick. Tears are healing. They are even more so when they are tears of Joy!
Things like that need to be shared. Because those tears can be attached to good and not so good memories and a sponsor can help you through it. Sponsors so often see what we can't see and know ourselves. They are our sounding board, and can be our safe place so we can share and not be alone.
