It was reasonable to leave him behind. Tim knew his parents still loved him but not in a way a parent would show love to their kid of course. It hurt a bit but it was fine. He was already used to it.
What wasn't fine was that he caught a cold and of course, Tim didn't mean to catch it so easily as he's been careful to not go around other kids at school or people nearby so how he caught it was unknown as he thought about all the possibilities to how the cold got to his body. The only final theory was that it was becoming more catchable during the cold season when Tim- who was unlucky- caught it.
Fortunately, Tim could go to the restroom to find medicine.
Unfortunately, there wasn't any when he checked and then he remembered that his parents hadn't got any even after a few times in the past he had reminded them.
What a bummer.
