Money. In our rhythm of life and its speed, many things change. Places of work, social circle, place of residence. People often move, change their circle of communication, and if you want the memory of you to remain, you need to give something worthwhile. In addition, do not give money for another reason - so as not to offend the person. Money usually means that you were too lazy to "sweat" with the gift or you just did not want to spend time on it, because it's easier to "pay off. If it is not a wedding gift to the newlyweds, then it is better not to give money.
