"I supported myself by casual and part-time work while studying."
"Shelf-stacker at Do-It-All. Seasonal caterer for a pub in Ballylynan. Pizza-Delivery boy. Telesales. Greasy insurance salesman. Cleaning gunk off machines in factories. Filing and microfiching insurance policies. Counting bolts in a warehouse. I am a Silver-Service waiter."
And I flatly deny that I have ever learned or written COBOL.
I suspect that there are far worse things missing from yours... Confess all.
