If I see actually this trend is more towards waste at the beginning of marriage. If the photo post wedding means the tendency is done not long after the wedding, but that period is a critical period.
The period after marriage should be used to discuss something more fundamental for the household. Many things to note, especially after the energy is drained to undergo a wedding procession.
After the reception is a fairly critical moment, especially for Indonesian people who like a scene when talking about marriage affairs. Weddings involve long preparations, high stress, and not to mention the many things that go wrong as planned.
The condition is very vulnerable for newly married couples. Conflict can happen. In my opinion, it would be nice if after marriage, the couple sat together for a chat rather than doing activities that are wasteful. For example, discussing the vision and mission of their household. Do they already know where the marriage is going.
