Hell naw, I know some people think it's shady, but it's not their right to know when I've read their text. Besides, a lot of time I like to think about how I want to respond. I don't really care about when they read mine. I'm good enough friends with the people I text that I know they'll respond.
Yes, i love letting people know i read it and replied. idk, i could never have it just be 'delivered'. it's too mysterious to me, i rather be basic and known
