I caught my roommate using my toothbrush to scrub his slippers

I no fit keep this one inside again. My roommate, Chuka, na correct guy but this one pass me. Two days ago I come back from class early, I no announce myself. I just open door quiet quiet. Wetin I see? Chuka dey use my toothbrush wey dey my cup dey scrub im white slippers. The slipper dey black with dirt. He dey brush am like say na im life depend on am.

I just stand there dey look am. When he turn he see me, he comot the toothbrush from slipper, put am back inside my cup like nothing happen. He even greet me with straight face. 'Emeka, you don come?' I no even answer am. I just collect my toothbrush, throw am for dustbin. Since that day I dey use my finger and salt dey brush my teeth. The man no even talk anything about am.

I swear to God, if you see the way he dey use that toothbrush dey scrub the sole, you go think say na professional shoe shiner. I don start dey hide my new toothbrush inside my bag. But the thing wey dey pain me pass na say he no even try to explain. Like say na normal thing. Na so so confusion for my mind. Which kind person dey use another man toothbrush for im slipper?
