When I graduated Highschool and turned 18, the changes were becoming more noticeable and my Mom agreed to let me wait an extra year to let the changes finish before leaving for University. I still needed time to fully adjust and become comfortable in public. My brother was working overseas and although he was concerned I hadn't answered any of his messages he seemed like he was having a good time.
