My best friend and I are very similar, and even have the same IQ. We used to spend a lot more time together and knew each other well enough to finish the most random sentences, and used to joke about it a lot. However since we left school it seems whenever one of us is feeling stronger or more intelligent, the other feels sluggish and drained.
It's not just an imagined reaction to the other's mood, as a lot of the time we find out through mentioning it on MSN since we don't meet up that often these days. Whenever one of us reaches a peak the other seems to be at the opposite, we're never both at our best or worst at the same time. Sometimes I wake up with extremely heightened senses, other mornings they're dull and distant, although both are fairly rare and I don't know how he feels on those days so I can't say if it's related.
It's not a problem all the time but when it does happen it's very frustrating on the negative end and I feel depressed, I think he does too when it happens to him. I haven't noticed whether or not it happens more at particular times or in particular circumstances, sorry I'm no help there. I'm not 100% sure this is the right place to post this so I apologize if I'm wrong, but if anyone knows why this happens or how I could prevent it I'd be very grateful.
