Most of us are keen to avoid drama when it comes to our wedding day, and sometimes that means not inviting certain people who are likely to clash and cause a commotion on our big day.
But what would you do if the people likely to beef are your best friend, your sibling, and your sibling's new partner?
For one woman on Reddit, it seems the choice her best friend made was to ditch her from the invite list entirely, as she's found herself banned from the wedding at the request of her ex-boyfriend, who is also the bride-to-be's brother.
The woman explained she had expected to be part of the bridal party at first, but was told that not only would she not be a bridesmaid, but she wouldn't be allowed to attend the ceremony at all - because the bride is worried her brother might be "uncomfortable".

In her post, the woman said: "I'm really good friends with the sister of my ex-boyfriend, Marina. Marina is getting married in December. As a friend, I assumed I'd be considered as a bridesmaid or at least be invited. I was excited to talk with her about the wedding plans.
"When she announced the wedding and posted the date on Facebook and Instagram I replied to her stories and I texted her to ask if we should go bridesmaid dress shopping. She then immediately video called me.
"She told me she was excited about the wedding, but sadly I won't be a bridesmaid. I was surprised considering we've been really good friends. I asked her why and she told me that she doesn't owe an explanation to me.
"I insisted because as a friend I think I'm at least owed an explanation about that decision and I'll respect it. She said it's because her brother's new girlfriend is going to be a bridesmaid so it'd be very uncomfortable for the ex to be there as well.
"She also told me I'm overall not invited at all because my ex is uncomfortable with my presence and she doesn't want to make her brother and his partner uncomfortable and wants this to be a pleasing experience for them."
And while the woman has claimed she's doing her best to be understanding, she find it "ridiculous" that she isn't invited just because of the bride's brother.
She added: "I tried to be understanding I really do but I told her how ridiculous it is that she's not inviting me because of her brother's discomfort and his girlfriend's insecurities and possible jealousy.
"[The bride] implied I'm an a** for assuming I'd be a bridesmaid in the first place, since she never made her intentions clear on whether I'd even be invited, and that I don't get to judge her choices."
Commenters on the Reddit post were baffled by the woman's actions, as many of them stated she was in the wrong for assuming she'd be a bridesmaid, and for not accepting her friend's decisions.
One person said: "I don't find it odd at all that she would take her brother's feelings into account, before yours. You should never just assume you'll be a bridesmaid. That puts everyone in a very awkward position."
While another added: "You said you'd respect her decision but you didn't. Also, it is a valid reason."
