Girls, Did I just screw up?

So there’s this girl I like and have feelings for. We’re just friends right now and we message all the time. Well I decided to get her a simple pink rose and leave it on her car to find when she leaves for work. I attached a note that simply said “I hope you have a great day). I signed my name at the bottom. She knows that I like her but we still talk as friends at least twice a day. But today after I left the rose she hasn’t said anything. Nothing at all. I don’t expect a long thank you or anything. But I do wish she would say something to let me know she found it. From a female perspective what is going on?
