Sometimes people might not reply back to you or answer you cause they know if they do then you will chat/text them for a long conversation which they don’t have time for. they love you & are still friends with you but they only have time for a quick hello, how are you & have a great day.
i.e. that why-sadly-lots of people text you instead of speak to you. its 10 times faster to text a question & be replied an answer then to call & take 10 minutes of chatting to get an answer. its sad that its become this way but that the new generation.
