So I went round to my parents and gave him the present my mother bought and the card that my gf bought and he asked me "Did you write the card yourself?"
I certainty did write it myself and told him so. I also asked him what my Mum had bought him (never seen it as it was at their house).
I was then told not to bother with cards any more as that card cost the same as a pint of beer and he would prefer a pint of beer.
I then wired up their new boiler and weather compensator.
The final job was to seal off their old washing mashing trap.
Tight to get to behind some kitchen units
but I think I have fixed it
I blocked the pipe with newspaper and then filled it with silicone.
Any problems with that? I would say job done.
