I Have My Ways

When someone is questioned on how he knows something or how he is going to get something done, sometimes he won't want to answer. Instead, he'll just utter the Stock Phrase "I Have My Ways". This cryptic response is unlikely to satisfy the asker for long, but it gets across the point that the asked person doesn't want to reveal the exact nature of their "ways" just yet.

Generally used in one of these cases:

The person being asked wants to keep the answer a secret, either because a source's identity needs to remain private, they don't want the other person to know how to get such information, or any other such reason.
The answer is so disturbing that the questioner REALLY doesn't want to know.
The person being asked is just going to make it up as he goes along.

Sometimes used as a Hand Wave. Not to be confused with We Have Ways of Making You Talk, which is about unorthodox torture methods.

Examples of I Have My Ways include:

In Homestuck, when John questions Rose about her information on the game, she replies "My perception of the future has been informed by other sources." These "informants" are primarily Doc Scratch and the Horrorterrors, neither of which John (or anyone except Rose, really) would be likely to approve of.
