Doodles (short)
When you were on the phone with some relatives, you'd often get bored and doodle on a piece of paper until the conversation came to a close. If paper was nowhere near you, then your hands would do. When on the phone with Justin you would usually doodle hearts and cute quotes.
When you went to meet Justin on the weekends, your arms would be decorated with flower patterns, quotes or your hand would simply be marked with blue ink from forgetting to close a pen. He'd smile to himself, wondering how lucky he was to have such a quirky girlfriend.
