I agree , there are positives and we will make a go of it come what may. It's what we do.
I can't imagine that anyone who has lived here for 16 years being required to leave. She and her family must surely by now be valued members of UK society but someone should reassure people in that situation that they will be welcome to stay. I can think of several people I know in the same position and it would be crazy to ask them to leave.
