False Front
A "False Front" refers to a deceptive appearance or facade that conceals the true nature of something. This term is often used in architecture, where buildings may have a decorative exterior that does not reflect their actual structure or purpose. It can also apply to individuals or organizations that present a misleading image to the public.
In a broader context, a false front can describe any situation where the outward presentation is not aligned with reality. This can occur in marketing, where products are advertised in a way that exaggerates their benefits, or in personal relationships, where someone may hide their true feelings or intentions.
