People come in all shapes and sizes, all colours and each one has too much baggage. Too late in life I discovered the secret and that is: when people attempt to negate your personal power, negate theirs by not caring because people want you to care.
Sadly, after spending too many years on this planet, I find I can count on one hand those worthy of my time.
A friend of mine introduced me to her favourite antidote to the dragging-on call. Mind you, it works better if you can do it in her sugar-sweet tones.
'I'm going to let you go now... Yes, I really must... Bye!'
Were you tempted to phone them back and put the phone down?
I have the opposite problem and repeatedly say 'okay, thanks, bye, yep, take care, bye...' hoping they'll put the phone down and let me off the hook.
