It’s Valentine’s Day, and the only real defense from a broken heart is anticipating the likelihood of something blowing-up in your face. Thankfully, one father-son duo came up with the perfect solution in order to keep your head dry duing tumultuous relationship related scenarios. The secret for successful dating (and anything related to attractions between yourself and the opposite sex) is to have parallel relationships – or, more clearly recognized as "keeping your options open".

Even before we try the (admittedly more complicated) calculations, we can already tell the situation has significantly improved. Because we’re dating in parallel, we compensate automatically for higher resistance. Even though Lisa clearly is just not putting out, the result isn’t the massive slow-down we saw before, but instead results in conservation of energy, as you expend less effort on a mostly dead branch and focus instead on more promising branches. Whereas before, Lisa sucked the majority of our energy, now Sally and Judy do—at 16.2 and 9 jewels, respectively.

A broken circuit also no longer really fazes us. In the case that one of the relationships completely evaporates (which, let’s face it, Lisa’s not heading in a good direction), we’ve still got other branches to take up the slack. Best of all, because Lisa was high-resistance anyway, her departure barely affected net current, which decreases from 3.1 A to 2.8 A—both radically higher than net series current.

I can’t imagine trying to justify your actions with this type of excuse after being caught by one or all of the girls you are dating at the same time. Ouch. I guess all the better-off without them if you lose each one altogether when you start to mention "parallel relationships", "circuits", and diagrams.
