You can choose to pay attention only to one part, yet you cannot expect that all the others cease to exist.
If you refuse to acknowledge the other parts, sooner or later, they will find a way to be acknowledged.
They will look for you in the parallel world, where all your attention is focused.
Then, they will receive your attention…
This has happened many times.
You did acknowledge them, at least for a few seconds, then you pretended nothing happened.
This pretense has become your reality.
Yet, no matter how long you pretend, they will find you again, probably also today.
Till you stop pretending.
