The head of a university dormitory is often the oldest and most determined person, and is also the best person to everyone, so you must buy a gift for her on her birthday.
1. The most precious gift is the sunshine that everyone needs, which cannot be bought or touched. How many people try to put the beautiful sunshine in a jar and give it to the person they care about to warm his/her heart. This small jar that stores sunshine will help you realize your wish.
2. Buy a metal makeup mirror for your good sister. Don't give a plastic one, but a metal one, preferably with diamonds, as such a mirror looks very classy.
Girls all care about their figure, so why not give her an electronic weight scale and put it in your dormitory so that all the sisters can share it.
