One of the things I like about fishing is the Long Silence. It only seems to happen while fishing, Hunting doesn't count because you have to be quiet to hunt. It certainly doesn't happen in golf.
Fishing by yourself is a Long Silence, but fishing alone doesn't count in the same way because its not a shared Long Silence.. It's only when you're fishing with a close friend or relative that it happens. And it nearly always seems to happen too. It happened a lot when I fished with my oldest brother, he was an artist at Long Silences. In fact he taught me about it when I was very young, shusing me occasionally as I rattled along with a motor mouth. A Most Valuable lesson in life.
You're fishing with your partner and you talk to each other, some. But then it happens, you both get quiet and just fish, lost in your own thoughts while still quite comfortably aware that you are not alone. Neither one of you needs to say anything for that Long Silence, you're just happy to be together fishing.
Even if one of you catches a fish, the other one only says "Nice one!". Then another Long Silence until the almost inevitable "Pass me a beer" comes along. Then the next Long Silence occurs.
I said I like them, but actually I love those Long Silences. They are not lapses of communication, they are communication at its apex. It is a form of communication that is above mere earthly words, it is a form of communication that is higher than the silence of a work day, more spiritual than the silence of a church. It is a shared time of minds that are equal in their awareness of the beuty of the present moment, the sufficiency of just being. Words only intrude, get in the way, bring the mind down to something less.
I know you've had Long Silences with your best fishing partners, although you may not have given them much thought. Now that you are perhaps aware of them, of their goldeness, conciously enjoy them as they come along.
You can make them last longer by getting your own beer. Another lesson learned by watching my brother.
