Why do you insist on being so dishonest, Oswald went home with Frazier each and every weekend but one, so much more than a mere "couple of times" and when Oswald's baby was born, he went to Irving on Monday afternoon and stayed till Tuesday morning.
So it was 4 times on a Friday. Yawn.
And the whole idea of going home on a weekend was so that Oswald could spend time with his family, like Friday night, all day Satu-rday and all day Sunday, so just spending a few hours with his children on Thursday night was hardly satisfactory.
Hardly satisfactory as decreed by "Mytton". Therefore, Oswald killed Kennnedy.
And especially just turning up without informing and clearing his visit with the owner of the house was just rude.
He was "rude", therefore he killed Kennedy.
Btw, it's odd that you find the most inane things to be highly suspicious but this glaring anomaly you lie about and try to make excuses, that says a lot!
What's inane is what you consider to be evidence of murder.
