Observation while being observed

Today I saw a robin sunbathing with its wings spread out. I was looking at it for a while, because it looked cute. Then it noticed me and reluctantly hopped away. I felt a little bad, because I was watching it like a weirdo. But I moved on as usual, and went to the backyard to grill some chicken. Then I felt like I was being watched and there in the corner of the yard was another robin. This robin was perched on a fallen branch and casually observing me. I stared back for a staring contest. All the robin did was brush me off, it looked in the other direction. I looked back to where the other robin had been sunbathing earlier, and it was still there but hiding in the bushes.
