As a bereavement counsellor I can assure you that numbness following bereavement is par for the course as are other seemingly inappropriate behaviours. This is why it is not thought to be advisable to counsel anybody until after the first anniversary is passed.
Does that include looking at one's watch at a funeral and declaring "Time's up!". Does it include pinching the waitresses' bottoms at a restaurant where champagne is ordered,does it include not letting one of the relatives inside the hearse leaving her standing outside in pouring rain because "she can go in the other car",does it include ripping up the twins' photograph at the Maida Vale flat,disposing of all Sheila's portfolio except one topless photo which he tried to flog to the Sun newspaper,along with another photograph showing Sheila wielding a gun as a prop,which he considered might have been useful to him?
I could go on about avoiding Auntie Pam and not sorting out his mother's things,as well as the tissue of lies Jeremy spreaded to anyone who deigned to listen to him..
