2.1b) How did people use to communicate through letters in the past?

 In the past, people communicated through letters by writing messages on paper and sending them via postal services. The process involved:

1. Writing the Letter: Using pen and paper to convey information, feelings, or requests.
2. Addressing the Envelope: Writing the recipient's address clearly on an envelope.
3. Stamping: Affixing a postage stamp to cover delivery costs.
4. Sending through Mail: Delivering the letter to a post office or mailbox for sorting and transportation.
5. Delivery: Postal workers would deliver the letter to the recipient's address, often taking days or weeks depending on the distance.

This method was reliable but slow, especially for long distances.
