Thank you all, not the birthday I was expecting as Paul twisted his ankle yesterday and it was really swollen this morning and he had to come down the stairs on his bum! I got him some Ibuprofen which is sorting it out. I was supposed to have the day off but went to work to be Paul's 'legs' but as predicted most enquiries were about plumbing which is not my area and poor old Paul had to keep getting up to fetch what was required.
