I nearly clicked like, but I couldn't. 
I have an older brother whom I don't get on with.  Communication is just occasional civility as we talk about Mum's wellbeing.  He's an estate agent with all the sereotypical traits present, a persistent shoe-polishing, mirror-preening, peacock-like, money-grabbing habitual liar.
On the other hand, I've had the same dentist for more than 30 years and I fear the day he retires.  He has never hurt me even once in all that time.
At one point he move practice in one direction, and I moved house in the other, and now a 90 mile journey does not deter me from sticking with him.  Fantastic dentist and a lovely man (see the link)  and I'm proud to know him - and his charges are reasonable too.
