I never got why people hold asking someone to prom on the same level as a marriage proposal. This isn't necessarily pointed at you seeing as other people have asked people to prom through elaborate songs or fireworks. But seriously, why not "Wanna go to prom."
Maybe I just feel this way because my school has very low spirit and the ASB only makes like 1-2 dances a year which nobody attends, not including prom, which people go to get drunk and partay.
