Common Sense
My boss thinks I am a fool. Yesterday he sent me to buy 2kg of sugar but I only found 1kg at the shops so I didn't buy. I went back to the office & told him that they only had 1kg. Very pissed at me, he asked me why I didn't use my brain and buy two 1kg packs to make a total of 2kg.

Today he sent me to buy a pair of Size 6 slippers but I only found Size 3. This time I used my brain and bought 2 pairs of Size 3 to make Size 6. I took them to him & he told me to wait outside. I can see him typing. I guess it's a promotion letter...```

Cleverness is killing me
