What do you think of "letters and text messages"? What are their advantages and disadvantages? Which one do you like? Great gods, help!

I like letters! Because people feel very real and warm! And some secret codes between each other can't be sent by SMS! SMS should have a specified number of words. And letters can speak freely! Letters can be collected! When you are old, when you start to miss it one day! Open the letter I received at the beginning, and everything seems to reappear yesterday! When I was in junior high school, I often corresponded with my friends and made pen pals! Those letters are still preserved today! Every time you open it, you will feel nostalgic!
