Life Decisions

So, In a previous post I talked about a girl whom I like but I couldn't tell her. So, I sent her roses anonymously although she figured it out that I'm the one who sent her roses but she didn't confronted me about this and was acting normal, talking about only Acads... So I asked her whether she received any flowers or not, and she responded with "ohh... That was you"... "I knew it"... (According to her she was shocked after figuring it out) I asked her how she figured it out, so she gave me some logic (crappy). And after that she asked me why I sent her roses... And responder because no-one else did. Ya... I'm joker... I believe... Any suggestions?
