What do girls mean by this? Girls please

I have an iPhone so I can see when people have read my text messages I sent them. A girl I'm talking to reads the message, but does not reply straight away. Sometimes she takes several hours to reply whilst other times like now she does not reply at all even though I have asked her a question. We're great friends so it is not like she doesn't like me. Why do girls do this?

Well… It could be that she looks at it and doesn't know how to reply so she doesn't (and possible forgets about it) or she doesn't feel that it needs a reply so she doesn't reply

Ok this might sound stupid, but still… It could be her wanting you to be waiting for her reply, sort of giving her more power, and for some girls that authority means a lot to them… I don't know if that's why she's doing it though… That's only some girls, so she could be doing it for a completely different reason, but I do know lots of girls who do this…

  • Why do girls take breakups so seriously? I just want to know out of curiosity, I mean why can't they be like me: shrug and say "S**t happens" and move on with my life without a second's hesitation. Are they so seriously immature that they need to completely blow things out of proportion? And seriously, what's with the post-breakup shenanigans? Breaking your ex's car or X-box or iPhone? Grow the f**k up and let it go! :L
  • Why do girls copy other girls? There's this girl I know and she 1. I colored my hair brown, so she did 2. I became a cashier at a grocery store, she did 3. Wore my glasses, so she did 4. Went to a facemakeover, she did 5. Bought an iphone, she did Those are just a few. What would cause a girl to want to copy you so much?
  • What does this mean: Free Msg: Receiver unable to receive message - Message Blocking is active mean on iPhone's iMessage? I tried sending my friend a text and it replied with this. We haven't gotten into any fights and we hung out for hours recently. Has she blocked me?
