TITLE: TIFU By kicking a random stranger
POST: Unlike many tifu, this actually happened today.
   I was walking into a meeting  when suddenly I see my friend Helen helping a handicap person out of her car. Helen and I have been long time friends for years, so naturally went up to her and was like, "Hey Helen!" For some reason Helen didn't answer me back or even acknowledge that I was there.  I stood behind her for a full minute and asked her if she picked out what college she was going to . Again she said nothing. At this point, the handicap person was out of the car and they started moving towards the building. Trying to get her attention,  I kicked the back of her boot and sarcastically  yelled, "Helen! Why are you ignoring me?"
   Suddenly Helen turned around but her face was completely different and a look of anger and horror went across this imposter's face. It was a complete stranger and I was mortified. Shock  began to settle in and I apologized profusely and tried to explain that I thought she was my friend Helen but it was too late...the awkwardness had set in. 
   The worst part of this story is that when I went into the meeting we had assigned seating and not real Helen and her handicap brother sat across from me and stared at me the whole time...
TL;DR: 
Thought I saw my friend and kicked her boots to get her attention. Turned out to be a stranger and is now mortified with me.
