I am in the minority here in that I believe a couple should not marry until they have the ability to be self supporting. It is not the responsibility of invited guests to ensure the couple has enough money to establish a household.
I am not against parents giving a helping hand (should they choose), but feel no obligation to finance a newly married couple.
Delay marriage until after your education is advanced enough so you can provide the necessities of food, clothing and shelter.
and contrary to commonsaychel’s opinion, Mrs. CTL enjoys choosing a gift for the couple getting married. We generally only give money to a couple who is marrying far from there new home and would find transporting gifts a burden.
