A successful proposal needs someone responsible for planning, someone responsible for purchasing, someone responsible for the scene layout, but also need a few people to guide the girl to the proposal site.
2, the purchasing person
A complete proposal, is the need to purchase goods, in addition to the most important proposal ring, the layout of the proposal venue or need more items, such as balloons, flowers, etc., so also need to purchase goods.
4. Co-ordinator
A complete proposal ceremony is a small (and possibly large) event, so someone needs to make the overall plan, do a good job of arranging and catching up, and adjust the plan in time to ensure that the proposal goes smoothly.
When everything is ready, we also need a guide to the girl, find an excuse to take her to the proposal venue, usually responsible for this job is the girl's best friend.
