UPDATE to add;
Thank you all so much for your insights.
I have stopped feeling guilty and will phone the person concerned later today or tomorrow morning. I know I may have been a little abrupt on the phone and caused distress if I took the call, hence I refrained from answering it !
Solitude, and a good brisk walk with the dog have restored my peace of mind and a rather more positive attitude :-)
I have just deliberately **not** answered the phone on the hunch that I knew the identity of who might be calling me. Dialling 1471 revealed the identity of the last caller, and I was correct in my assumption.
I simply could not face having a long involved conversation with this person today. I just feel stressed, harrassed, slightly under the weather, and a bit fed up. Nothing major, just bleuch.........
I would really like to have some peace and quiet and relative tranquility whilst the small ones are at school today, to brace myself for the baking session the young ones and I have planned for after school.
And of course now I am feeling profoundly guilty because I didn't answer the phone.
It is going to be one of those days.
