intrude (up)on (someone or something)
To involve oneself in something in a way that is meddlesome or unwelcome. I really try not to intrude on my kids, even though they think I'm too involved in their lives. I accidentally intruded upon their seminar before it was over, oops. I didn't realize it was three hours long!
