Epic fail.
Everybody makes mistakes, so it's typical to have uncomfortable moments in our daily life.
One day I was walking on the street and I saw a girl that looks like my friend Laura. I started runing to give her a scary hug from her back. As you can imagine this girl was not my friend, so I scared a poor girl. I imediatly sayed sorry and explained the situation to her. Fortunatly she understanded the situation and only laught of it.
Probably I have had best embarassing moments but this one is print on my mind.
I really like your thoughts, I agree with you in reference with bring our mobile phones with us.
