"Sherlock, is this really necessary?" John sighed as he finished packing his last suitcase. He looked at Sherlock, who was waiting by the door of 221B Baker Street with his own suitcases near him.
"Absolutely John, you are getting married in four days and I insist that you have the best vacation and party." He said with a smile. He walked over to the window upon hearing the sound of a car parking.
"I'm glad to hear you say that Sherlock." John said, trying to hold back a laugh.
"Why is Mycroft's car here?" He looked at John suspiciously, but the look on John's face made him realize what was going on almost instantly. "You invited Mycroft?"
"Yes, I invited Mycroft! You invited Lestrade!" John snapped back.
"Yes, because I actually somewhat like Lestrade. He can be useful." John sighed at his flat mate but eventually just smiled and laughed.
"You'll have a good time with Mycroft; don't let him ruin your whole trip."
"You invited my own brother without consulting me! How would you like it if I invited Harry?"
"It's irrelevant, he is invited and he accepted. You have to deal with that, so stop sulking like a child!" Sherlock was taken aback by John's sudden outburst. He was about to answer when Mycroft and Lestrade walked in.
"Hello Sherlock." Mycroft said to his brother. "I imagine that you did not particularly want me to come along with the three of you, but seeing as that is not your decision, I am sure you will be able to deal with it eventually." Mycroft's statement was followed by muffled laughs from both John and Lestrade.
"Hello Mycroft, and no, I did not want you to come along. However, seeing as this is John's party, I'm sure we can make the best of things." John looked at Sherlock wide-eyed before finally speaking up.
"All right, does everybody have their luggage ready?"
"Mine and Mycroft's are in the car. You're lucky I was able to get off work for the week." Lestrade said, just as Mrs. Hudson walked up the stairs to help with John and Sherlock's luggage.
After about 10 minutes, all of the luggage was in the taxi and in Mycroft's car. John and Sherlock rode in the taxi while Mycroft and Lestrade went in his car.
"Be careful, all of you!" Mrs. Hudson waved goodbye to them as they drove away.
Upon arrival at the airport, the four men got out of their cars and took their luggage through security. Sherlock had to be patted down by the guards for setting the metal detector off.
As it turns out, the airport doesn't like it when you try to bring metal jars filled with unidentified liquid inside. They confiscated all of his jars and Sherlock was able to board the plane. He quickly caught up with the other men who were waiting for him.
"I just wanted to perform some experiments during the trip." The men all laughed at this. "How long is the flight anyway?"
"About 11 hours." Mycroft replied. Sherlock rolled his eyes and boarded the plane with the others. He sat quietly at his window seat when a familiar voice sat next to him.
"Hello again, brother." Sherlock looked at Mycroft, with a look of complete disappointment.
"Please don't tell me I have to sit next to you for 11 straight hours."
"Okay then, I will refrain from telling you." Sherlock buried his head in his hands and tried to think of anything he could do to get out of this situation, but every option seemed futile. Sherlock heard John and Lestrade giggling behind them and he turned around and shot them an evil look.
