Does this mean the person was online?

It looks like she has been playing a game, but sometimes people play games and don't want to look at their messages and notifications, they just want to play. I have had problems with messages a few times, I didn't receive one until about a week after someone sent it, she may just want to escape and so just played a few games or it could be she hasn't got the message.

Edit: I've not been 'poked' for a while, so I'm not sure, I think they come up straight away, but can't be certain. Don't feel silly, if you're not sure how something works it's always best to ask :-)
