@max: What do you think Mrs Crusty would make of all this?
Can you remember Mrs Glum from the radio programme "Take It from here"? It may be before you were a twinkle in your mothers eye? However Mrs Glum was always a noises off and Mr Glum (Jimmy Edwards) interpreted these noise as Mrs Glum disagreeing with his decision or plan. I think the Mrs Crusty we allude to here, would have the same opinion as Mrs Glum, perhaps not very dissimilar to your Mums view on this subject which might be "Silly men"? :-)LOL
