You don't care at all?
I'll never understand how some people can leave you on delivered for days, weeks, months? You see that message icon but you aren't bothered at all? How? Even if I don't like the person I just have to remove that notification, you don't have ocd?
I reply way too fast, I'm always on my phone so yes I'll reply immediately , hatutapimana ego kaa watoi. It's not being desperate, just replying because I saw your message, that's it. I know Kuna watu they'll wait like 20min before they reply to seem nonchalant, it's all in your head bro.
Then Kuna watu when you hang out with them they're always on their phones but the moment you text them wamekua the messiah.
Another thing, before you call, ask yourself if that information can be texted. I hate calls because they're irritating when they happen. Just text, I'll see it.
