Whenever I fill out one of those stupid surveys and it asks what I am looking for in a significant other I usually put humor or honesty or some funny answer. But really, and this is no big breakthrough but, in any relationship, whether it is platonic or romantic, communication is so so so so so very important. And I'm even getting as deep as talking about communication of feelings and thoughts and fears, etc. Just keeping in touch with friends and significant others, and even family, is so necessary.
It is a special relationship with someone when we can go for awhile without talking and have everything be normal when we reconnect. Other friends require more.
I tend to get paranoid that someone is mad at me, or that I did something to warrant the silent treatment. Even if I did nothing (which is usually the case;) I start crafting apologies for random things: "I'm sorry I send you 3 emails in a row," "I'm sorry I made you drive the other night," "I'm sorry, I didn't mean to make that situation awkward."
It's stupid, I know. I'm pretty good at reminding myself that I'm being stupid though, so it all works out. But a little part of me can't rest easy until communication is back to normal...
