You really should though. Not ending with a period just looks… off. And there’s really no reason not to, on phones, the period is generally right next to the send button on mobile, and it takes pretty much no extra effort on a regular keyboard.
Stop being lazy and actually end your sentences…
I think you thinking people are lazy for not typing the way you do says more about you than it does about them ;)
Informal text communication has increasingly played with punctuation and grammar to indicate tone, emotion, and cadence. This has been happening for decades. Language is a tool that is fluid and malleable. There are only rules insofar as there is broad consensus on how language works at the moment. Stop being a weenie
It probably has to do with strict character limits and the habit spreading. Twitter is only, what, 156 characters? I know text messages used to be something similar, and early on, they cost around 3 cents a letter and you had to hit the numbers multiple times to cycle through to the letter or punctuation that you wanted. It’s where stuff like l33t speak came from, at least.
Fair. I grew up with 140 character limits for SMS and having limits on how many texts I could send, so I get it. But instead of cutting out punctuation, I used more direct language and abbreviations. Now that there’s no real limit on texts, I’m a bit more wordy and am extra careful about punctuation, especially since I use swipe texting.
If you’re typing a single sentence it’s pretty common to leave out the period, this just keeps it consistent
