Girl from high school

So a highscool friend that I haven't talked in like 3 years texted me wishing happy bday she used to be very sarcastic so I replied with:
Thank you cutie
Where is my gift?
She: I have it with me. I'm coming to your city to give it to you
Me: since you are coming you know what we should do?
Her: what?
Me: Hang out for the good old times
Her: I think I'm going to "my city"
Me: Hmm you don't sound confident
I'm never sure what to do with maybe, I think, I guess responses, so I just said "you don't sound confident" its been 2 days no response
Any ideas how to proceed?
