I'm an undergraduate student at a research one university. My former instructor and current research mentor is defending their dissertation soon. I asked if I could attend and they said they would be fine with it.
My primary interest in doing so is to see how the defense process works for when I attend graduate school. I am also just genuinely interested in supporting them since we both research the same material and they've been incredibly encouraging and helpful to me.
I know defenses are open to the public, but, in your opinion, would a student attending your defense add more stress or disrupt the process? I just want to make sure I'm not making anything more difficult for them or overstepping a boundary, even though they say they are totally okay with me attending.
