Touch and go's are very common w/the MLCer. Sometimes, they will come around and have moments of clarity, whereby they may show interest in you or what you are doing and then they disappear again for a period of time. It's their way of checking to see if you are still right where they left you. They can sense when you begin to pull away and begin moving forward and often times, that's when they'll come around a bit. They may actually talk to you like a rational person, show interest in you, etc., of share tidbits of their life w/you...however, once they come to realize that they are warming up to you again...off they go again. We call their actions "temperature checks".
I have never heard the term "anchor check". Sorry.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
