A man is explaining something to a wall. He is gesturing towards the wall with a pointer, fully engaged in his discussion. His expressions illustrate his enthusiasm and focus, even though he is talking to an inanimate object.

A middle-aged man with spectacle is passionately lecturing to a crimson brick wall. He has a wooden pointer in his right hand, extending it towards the wall as if pointing at a crucial detail. His face displays intense concentration, his eyebrows furrowed, lips partially open to let out words of explanation. His free left hand is animated, punctuating his speech with compelling gestures. His level of engagement is palpable, despite the fact that his audience is merely an unresponsive, inanimate brick wall.
