Sometimes one email can change the whole perspective of a day. What a lovely email to receive on a Monday morning: 

Dear Jackie

Seems incredible but we are now booking holidays in 2019. So please can you book a minder for us from March 26th to April 2nd, obviously flight times are not yet available but hope this will be accurate and I will confirm them as soon as we are given them.
I would like it to be either Carol or Roger Tucker if either is available as they get on well with our dog and it is nice to have someone we have got to know.

Many thanks for your help and we have always been very pleased with your service over the years. I’m sure not enough people say thank you but take it for granted. I just wanted you to know how grateful we are that this service is provided for us and give us peace of mind while we are away.

Best wishes
