This bride (under the pseudonym OP) proved this to be true after she asked her own sister, who was also her maid of honour, to leave her wedding for allegedly "stealing her spotlight" during and after her speech.

According to Fox News, the bride posted to Reddit to ask fellow users whether or not she had been wrong for chasing her sister away from the wedding after she had "made her entire speech about herself and her mental illness".

The post read as follows, "My sister was my maid of honour. During her speech, she brought up her depression and how my husband supported her through it and how “in that moment, I knew he was the one for throwaway...” (so cliche!).

I thought her speech was really selfish. I think it’s super inappropriate to bring up a mental illness during a wedding speech.

Not only that, but the entire speech was about her. At MY wedding. Ninety percent of the guests congratulated her afterwards and talked about how “strong” she was. Nobody was paying attention to me, at my own wedding!

Sorry if I sound selfish, but IMO (in my opinion) there is a time and a place for this sort of thing. So after the guests all greeted her, I asked her to leave and told her she was being disruptive and selfish.

She was really upset but just left without arguing. My parents agree with me, but my husband and all of my close friends think I was way too harsh."

Some Reddit users were quick to point out that the bride was indeed very selfish and many of them could not even believe that she had asked her own sister to leave for mentioning her mental illness.

"Does she not realise this is now the one thing people will remember about her wedding? How she went all jealous gorilla and locked her sister out. Like, wow OP. They're gonna talk about this for years." wrote one user.

This user commented, "OP's sister was really putting the focus on how supportive her new husband was. There was no intention to steal her spotlight at all."

Another commented "She made a mistake so she was punished in that petty way only a bridezilla can be. Strange how every major event in a woman's life is "ruined" by another woman."

While other users agreed with the bride, calling it "inappropriate" to speak about mental illnesses at certain functions.

This user said, "I want to disagree with your "selfish" analysis. Weddings are a celebration of the bride and groom. Being upset for someone stealing the spotlight isn't unreasonable."

While another commented, 

"Weddings aren't the place to bring up mental illness. Mental illness isn't a trophy you carry around and show everyone."

Other users questioned how the bride's parents could agree with her kicking her own sister out of the wedding.

"I think the fact that her parents agreed with her throwing her sister out probably speaks volumes about the situation and family dynamic", wrote one of the users.

The bride has not replied to any of the comments made by Reddit users but has hopefully given her sister a much-needed apology.

While weddings have always been a cause for brides to go a little cuckoo because they want everything to be perfect, I do agree with most of the Reddit user comments that chasing her sister away over a speech that she considers inappropriate was a tad extreme.

Surely expressing her dismay at the speech and moving along with the festivities would have been enough?
