Bob friends? Is that another guy named Robert?
Yes. Seems a high proportion of my male friends are Roberts.
One day about 25 years ago some of us were playing Illuminati at Bill's: Bob, Bob, Bob, and Bob. We thought maybe Bill should've changed his name to Bob for convenience.
To my immediate family, I was always Robert. To my cousins, aunts, and uncles I was always Bobby or Bob. The cousins my immediate family referred to as Bobby or Bob were Robert in their respective immediate families.
People phone on business here and ask for Robert. I have to ask which Robert they want. Our last names end in -man.
