You must have experience in getting married. You can tell him what to prepare. For example, when shopping, you can help him suggest what he needs. See if he has arranged everything for the wedding and prepared enough cigarettes, wine, tea and sugar. You can help set off firecrackers at the wedding and find some buddies to set off the atmosphere. You can take a picture of him as a souvenir. You can also organize a bridal chamber at night. The wedding must be lively. Just try to help him do some trivial things. Friends will be very happy. If you can't make a wedding, organize a few meetings. )
