What is an informal note?

An informal note is a casual, often handwritten message that conveys personal thoughts, reminders, or information between friends, family, or acquaintances. It typically features a friendly tone and may include anecdotes or personal touches, making it less structured than formal correspondence. Informal notes can be used for various purposes, such as invitations, thank-you messages, or just a quick hello. Overall, they prioritize warmth and personal connection over formality.
