Is it acceptable/mature to ignore somebody? ?

My dad ignored me for a while after he found out I had gotten a large speeding ticket when I was 17. When I was 18 he ignored me for what seemed like a month because I got a tattoo. Ignoring someone doesn't change anything. The problems are still there and the upset feelings are still lingering. Unless you talk things out they will still be there. If I ignore someone it is because I have to calm down so I can properly talk to them about the situation.
