I would just like to add a postscript to Twilight’s brilliant post.
A friend of mine is being sent texts that she doesn’t like, often during the night which disturbs her sleep. I told her to leave her phone off at least during the night. She said ‘BUT I have to keep in on in case my son who lives on the other side of the world wants me or my daughter needs help with her children. It is always the ‘but’ that leaves the door and yet it wasn’t that long ago that parents and children could not keep tabs on one another because there was no such thing as a mobile phone. I would imagine this is one of your concerns and my suggestion would be to tell your other children and friends another way of contacting you – even changing your number.
If there really was an emergency you would be found, just as children and their parents used to be in the not so distant past.
