Need help understanding female texting. Is there a good busy and a bad busy?

an old friend of mine (a lady friend) has texted back to me after I didn't respond to her for a long time (told her I was busy) and she said hopefully it is the good busy. When I clarified she said that’s good, and then When I asked about what she did recently, she said β€œa friend took her to an island on her birthday,” with an πŸ™‚ emoji.

When I did wish her a happy birthday on her Facebook, I made a joke about not eating all the cake and she said thank you and replied with πŸ˜ŠπŸŽ‚πŸŽ‚πŸŽ‚.

I am certain I am reading into it too much and it means nothing at all but I just want to know what it all means, especially the good and bad busy because the other stuff I can assume is just her being friendly/playful.

Thanks in advance for the answers.
