Linguists trace the adoption of phrases like "idm" to an ongoing shift in how society displays consideration. Historically, politeness required formal verbosity: "I would be entirely delighted with whatever option you select." Digital messaging inverted this convention. Today, brevity often signals respect for the recipient's attention span.
Modern communication values frictionless back-and-forth. By using casual abbreviations, senders strip away artificial formality to simulate real-time vocal cadence. "IDM" sits in the same category as "NBD" (no big deal) and "NP" (no problem). These phrases minimize social debt, reassuring the other person that their request causes zero stress or inconvenience.
