Answer:
dnd
Explanation:
What saves time and characters, when cell phone users want to say "bye," they type "DND."
This is because DND in texting means "DO NOT DISTURB" This shows the conversation has ended for the moment and the other party or recipient of the message should not disturb the messenger with additional text.
A3 in texting means: Anywhere, Any Time, Anyplace. This is not the correct answer
A2 in texting means Alpha 2
TMB in texting means: Text Me Back.
