Elderly people may seem frail, but messing with them is never a good idea. Though their bodies have aged, their minds are still sharp as a whip, and their lengthy life experience gives them an upper hand in many situations.

The following letter was sent to a bank manager by an 86 year-old woman after her check bounced, and he thought it was so funny that he sent it to the New York Times to publish. The letter is sure to bring a smile to your face and serve as a reminder that messing with older people is a very bad move indeed!

Here’s the full letter:
“Dear Sir: I am writing to thank you for bouncing my check with which I endeavored to pay my plumber last month. By my calculations, 3 nanoseconds must have elapsed between his presenting the check and the arrival in my account of the funds needed to honor it..
I refer, of course, to the automatic monthly deposit of my entire pension, an arrangement which, I admit, has been in place for only 8 years.
You are to be commended for seizing that brief window of opportunity, and also for debiting my account $30 by way of penalty for the inconvenience caused to your bank.
My thankfulness springs from the manner in which this incident has caused me to rethink my errant financial ways. I noticed that whereas I personally answer your telephone calls and letters, — when I try to contact you, I am confronted by the impersonal, overcharging, pre-recorded, faceless entity which your bank has become.

From now on, I, like you, choose only to deal with a flesh-and-blood person.
My mortgage and loan repayments will therefore and hereafter no longer be automatic, but will arrive at your bank, by check, addressed personally and confidentially to an employee at your bank whom you must nominate.
Be aware that it is an OFFENSE under the Postal Act for any other person to open such an envelope.
Please find attached an Application Contact which I require your chosen employee to complete.
I am sorry it runs to eight pages, but in order that I know as much about him or her as your bank knows about me, there is no alternative.
Please note that all copies of his or her medical history must be countersigned by a Notary Public, and the mandatory details of his/her financial situation (income, debts, assets and liabilities) must be accompanied by documented proof.
