However, it is important to note that P. S. should not be followed by a comma. Neither “PS,” nor “P. S. ,” are considered proper ways of introducing a postscript. Use “PS” if you are using the Chicago Manual of Style, which suggests it as preferable to “P. S. ”
While adding ‘P’s can be necessary, the tone is cute and can be almost cheeky or silly, so anything more than a “P. P. S”, like “P. P. P. P. S. ”, should most likely be reserved for personal messages or light-hearted correspondences with colleagues and peers. Note that contrary to common usage, the next level past P. S. is not “P. S. S. ”, which would be the nonsensical “after-writing-writing”.
In a personal message, a long P. S. simply suggests that you remembered something else you wanted to mention. You should not be afraid to include a whole new story in a P. S. to a friend or loved one.
This is a classic way to use a postscript, as in the case of “P. S. Say “Happy Birthday” to cousin Katie for me!”[5] X Research source
The familiar nature of the postscript means it is a good place to include humorously sarcastic comments, e. g. , “P. S. Still haven’t heard whether you want me to purchase the Eiffel Tower for you…” or “P. S. Let me know how Paris looks on a warm summer evening. I hear it’s pretty terrible. ”
For instance, “P. S. I haven’t read the book you gave me yet, so I will let you know what I think when I am finished. ”
“P. S. Ask Maisie to read this, please,” for instance, would not feel out of place after the letter, but could cause confusion in the middle or at the beginning.
For instance, a message about correcting a minor procedural error can be softened with an appreciative P. S. about something your colleague has done recently. Be careful not to accidentally create a facetious tone. If your message is stern or assertive, a kind P. S. can feel like a mocking joke or a slight directed at the recipient.
Try breaking the message into two parts or sending the messages separately.
For example, saying “P. S. Sorry to reach you so late on a Friday, feel free to respond on Monday. Enjoy your weekend!” can help alleviate any tension that could have come from the situation.
You should not rely on the P. S. to hook readers. Your opening should be strong as well.
Don’t restate everything, just provide a general outline.
Including important information in the P. S. as a reminder is a more traditional use, not backed by assumptions about what part of a message is read first.
