First, the necklace is a gift that girls can't refuse. I'm still wearing the necklace my boyfriend gave me in my first year. It's not expensive, but he shows sincerity, so I will care if I wear it every day.
Second, the new mobile phone is for girls who just need it. For example, my mobile phone has been used for two or three years. My boyfriend gave me a new mobile phone this year, and it feels like it's in my heart. Then this gift embodies its value and shows the boys' intentions.
Third, watches are personal belongings, and girls love beauty. What's more, for young people in the workplace, watches not only have a concept of time, but also can always feel your love when you wear them before going out.
