The pressure and loneliness of graduate students for several years are very difficult, and the people who accompany them really pay a lot and should be grateful. However, many schools have advised against this, fearing that they will not make it to the end and look embarrassed. Actually, it's not. It's also a commemoration that we didn't go to the end together. If it is embarrassing, it is that we don't know about it.
Noun explanation:
Thanking your partner or spouse is a romantic thing, and as a person around you, writing a paper with yourself is an unthinking encouragement, and trying to think back and forth together is actually an affirmation, not to mention thanking your partner is a sign that you don't care. This may not be right, but you won't write if you don't care about the high probability.
