For some obscure reason 20 years ago they moved from Peterborough (admittedly a heinous place) to Scarborough to retire ...which given that it is on the A64 largely single tracked road might as well be Outer Mongolia ...(at the time I was living in Leicester and brother in Birmingham)
Anyways - they were invited to come and stay with us (south coast - 275 miles distance between us) for 3 or 4 days next week to coincide with ds's 7th birthday and indeed mum's birthday (15 April). Haven't seen 'em since Christmas. So mum rings me tonight - 'we are not coming after all because your dad has a bad back and so do I....'
Now they are old - 77 and 82 respectively, and it is a hell of a long way to drive at their age....but in the past we have frequently offered to pay for train tickets and to pick them up from London so they don't have to change trains etc...
Why don't they want to see their grandson on their birthday?
