Mostly As: You are an I2C bus. You allow many devices to share only two wires via an addressing scheme that never quite works the first time. Your need for pull-ups and your tricky state dependent interrupts are often a turnoff, making it tough to have a good meet-cute. But when someone want a lot of devices without a lot of wires, you are a great choice!

Mostly Bs: You are a SPI bus. You are easy to learn and fast, lots of fun in all. Sometimes you let the mess of wires get out of hand, consuming too many precious processor pins. Still, as everyone's first crush, you are always thought of with fondness.

Mostly Cs: You are a CAN bus. Known for your automotive industry experience, you are a useful, robust, and interesting protocol, often overlooked. External aggravations don't upset you easily. You only hear what you want to hear, when you talk you are telling others about yourself, but know your place in the world. While you seem to have more layers than an onion, you aren't that difficult to get to know, plus you are great on a resume. 

Mostly Ds: You are a serial port. You are not old, you are classic. Right? Your consistent simplicity is beloved by developers everywhere. Don't ever change. 

Mostly Es: You are USB. Everybody likes you until they have to work with you. Then they realize that your easygoing personality hides a megalomaniacal dictator. Worse, no one can decide which way is up with you and your cable proliferation is simply out of control. Be careful, your willingness to share power may make others use you for their own ends. People should like you for yourself (and your high speed data throughput).
