A while ago I ran across this:

In the interview, Michelle Obama described a fairly recent incident where she experienced racial prejudice:
The first lady also described being mistreated at a Target store in suburban Washington, during a shopping trip she took in 2011.
“Even as the first lady,” she told the magazine, “during the wonderfully publicized trip I took to Target, not highly disguised, the only person who came up to me in the store was a woman who asked me to help her take something off a shelf.”
She said the incidents are “the regular course of life” for African-Americans and a “challenge” for the country to overcome.
The horror! Can you believe “can you help me reach that” still exists in 21st century America?
For the record, I’m a 6’3″ white guy and several times in my life I’ve been in a store and been asked by somebody if I could reach something on a shelf for them — and I had no idea until now that I’d been the victim of racism. Michelle Obama is almost 6 feet tall so I’m sure it’s happened to her more than once too, and I’m guessing most of those weren’t because she was black, but rather tall.
Clearly America has a problem with heightism!
Update:
Funny how FLOTUS’ take on the same story has evolved in just a couple of years:
2 years ago @FLOTUS described helping the woman bc she was short
Today, she claims it's racism http://t.co/gsEhiD8sSj pic.twitter.com/8HI8m5Uacz
