Input: I recently invited a three of my good friends to go on a snowboarding trip last week. I told the three of them that to give me suggestions of people of who I should invite as well. Well they suggested a mutual friend, lets call him Sam, and that they all wanted to come along with us. We all, including Sam, frequently played video games together and hung out together occasionally. However, I disliked Sam because of reason such as him being obnoxious and often oblivious to his suroundings which caused him to be a pain to hang out with. Therefore, I told my friends that I did not want him to come because of the said reasons, which they agreed to. Well, as you can tell from the title, Sam shows up to the ski resort. Intially, I thought Sam showed up by himself but found out that my three friends invited him behind my back. I was initially angry but unwilling to ruin the trip when along with it.
