“Dear friendsfirst team, I enrolled with you for a year’s membership and have chatted to a very nice gentleman, however I have since had contact with another gentleman on a regular basis (who happened across my path) and, as this is developing into something close, I feel it would be wisest to ask if you would remove my name & details from the circulation list.  I would appreciate your keeping in contact with me for the duration of my membership in case these circumstances alter.  Thank you for your courtesy and professionalism throughout my limited experience of your services.”
