My Artistic Secret Crush

Hey there! So here's something I've been keeping to myself lately. I have a secret crush on my art teacher, Mr. Thompson. It's not romantic or anything, but he has this way of making me feel seen when I'm struggling with a piece. He just gets it and gives the best feedback ever. But there's one weird part: every time he talks to me about my work, I get all jittery and start drawing silly cartoons instead! Is that normal? Should I tell him how much his encouragement means to me or keep it my little secret?
