My 11-year-old cursed at me. Should I let it go or draw a line?

Dear Meghan: My 11-year-old used some cuss words last night to express his anger with me. Thoughts on circling back on this today? We’ve told him words are just words, but there is a time and place for certain words. We’ve talked about cuss words being disrespectful in most cases.

I don’t want to spotlight this to make it a recurring behavior … but obviously I think it’s important to draw the line. Thoughts?
