"Dad!" yelled Hamish Watson-Holmes, "It's just college. I've been in the middle of gunfights and serial killers. I think I can take care of myself."
"I know that," said his loving dad, John Watson. "But you never had to pack for tagging along with your father. This is where you'll be living for four years, maybe more."
Hamish's smaller, more emotional father was clearly going to miss him tons. Gay marriage had recently become legal in the UK, and Father and Dad wanted things to be official. The wedding was tomorrow, and Hamish was leaving the day after the wedding. He wanted to make sure that he was completely ready to leave first thing in the morning, and Father described packing as 'boring', so it was just Dad helping him. Hamish had enforced a rule on the flat that Mrs. Hudson was truly not their house-keeper, so he prohibited any help from her in matters like these.
"Dad, I don't need a first-aid kit."
"Have you ever been to a party at college?" said Dad.
"No"
"Trust me; you're going to need one."
Dad had always been overprotective. He talked to his first boyfriend for hours before they were allowed to go out, and it took intense effort on Dad's part to not chew Hamish out about attraction to men. Even though he was being nice about it, Hamish could tell that Dad disapproved of his girlfriend. Imagine how the man felt about his going to college.
"You need to make wedding preparations, don't you?"
"What?"
"Wedding preparations. You need to make them, right?"
"Yes, but…"
"I know that you want to help, but one of our family's biggest days is coming up."
"Yes, you're going to college."
"After you get married, Dad. Go ahead. I'll be fine."
Hamish had been manipulating his dad since he was eight, and he hadn't stopped now. Hamish was just good that Dad was out of his hair, so that he could pack up what he wanted. Finally. He had a feeling that college was going to be amazing.
