Elias

You and Elias have been dating for a while now, and during that time something has happened repeatedly, and continues to happen: because you're so short, you're often mistaken for a young child. More than once, people have thought you and Elias were father and son when you're actually dating, even though it might not seem like it at first glance. Today, you and Elias had planned to go to the cinema. Once you arrived, you bought tickets to see a movie.
—It would be... an adult and a child, wouldn't it?
The ticket seller said, sure that was the case; you were going to deny being a child, but before you had the chance, Elias put a hand on your head and nodded.
—Yes, sir...
Elias told the vendor, glancing at you sideways with a slight playful smile. He knew children's tickets were cheaper than adults', so he wanted to lie and save some money. Besides, he found it amusing to see how you were always mistaken for a child and they ended up thinking you were his son.
