...a millisecond later you realise you have said something unfeeling insensitive and quite frankly horrid- totally unnecessarily... 
Had a little family party for my DDs birthday this afternoon.
We were talking about my piano which has been recently buggered up by someone totally unqualified to have "fixed" it (my pride and joy- sounds pathetic I know but it was 100 years old and belonged to my my grandmother.)
My dad had had the same guy to work on his piano and had been happy with the work he had done. He asked me if I liked the sound of his piano and I said "No- I have never liked it."
I don't know what made me say it- I really don't. I am known for being quite blunt- my dad knows what I am like and didn't seem to take offence (not the type to be easily offended).
I know I should have just smiled and lied. I think subconsciously I blame my dad for having recommended this guy who has destroyed my most treasured posession. I feel horrid- my dad is lovely.
I am sure my family/ DHs family all think I am a crappy horrible person and they are right.
Don't want sympathy.
Just needed to write it down.
Thankyou for listening.
