Well, I am very particular about communication skills and giving fast, quick replies. To answer your question, I always give timely, fast and quick replies and for that I don't have to like any woman!, I do that because that's a moral I have and it's my character, hence I do that even if I don't like a woman.
Speaking about woman in general, I always make sure that I never leave anything unanswered if a woman has asked me something and I make sure I reply quickly.
Yes, on rare occasions there will be a minor delay say 2 or 3 days or if I am sick, because I am also human after all. However as I said delay on my part will be a rare thing as far as communication skills are concerned.
I am VERY OFTEN too busy to reply, and I tell any girl I date that fact at the very beginning. I actually took a girl to work one day and she got to see what my days can be like, and she never complained again. I often work 12+ hour days, and most of them I'm either driving (and in a hurry), talking to a customer (who expects my full, undivided attention), or on a ladder/running wire/using tools. I don't sit at a desk all day and pretend to work for 4 out of 8 hours like some folks I know.
there's only one guy busy enough not to reply in 24 hours and thats the president. If it says on messenger/whatsapp/kik/viber/whatever that he is online, or comes online every now and then, he is ignoring you or he didn't see your message. The latter is highly unlikely. If I like a girl, ill talk to her as much as possible, thats for sure
