You would think that a woman who is carrying her child wouldn't want to be around somebody who has a serious illness, but I guess she cares more about the party than she cares about the baby's safety. 

I love to host parties. Every couple of months, my roommates and I invite our 200 closest friends to our apartment for a themed house party, and at least 60 of them show up without fail. We have developed a reputation for hosting pretty fun parties. Zack, my roommate who is great in the kitchen, makes a huge vat of special-flavored punch for all the guests, so we never run out of what keeps the party going. My other roommate, Audrey, loves to transform our space, and she makes incredible decorations that really set our house parties apart from others. I invite the majority of the party guests, mostly members of my adult recreational sports league. When we work together, we can create something wonderful. I am grateful to have roommates who are not only comfortable with us hosting parties, but also willing to put in the work to make them great. 

Over the years, I've learned you really can't be too sensitive about people bailing on your events, especially house parties. Even though I know one person not showing up won't totally change the event's trajectory, it still sometimes hurts my feelings. The worst part of the party planning experience is an hour or two before it starts, when people start sending you paragraph-long texts about why they can't make it. I know not everyone would agree, but I would rather party guests not show up than try to justify bailing. I would understand a long text explaining why you're bailing on an intimate dinner, but for a big party, I don't think it's a crime to just bail without explaining yourself. The worst is when people go from RSVPing "Going" to RSVPing "Maybe" on the day of the party. At that point, just RSVP "Can't Go," and move along!

Even though I am a little sensitive when people bail on my parties, I know my party isn't the most important thing happening in their life right now. If someone is sick or not feeling up to it, I would never judge them for skipping. I know a 27th birthday party isn't that big a deal, so I won't judge my friends for putting themselves first. 

Some events in life you really want your friends and family to be there for. If my best friend missed my baby shower or my wedding because she had a slight cold, I would be pretty upset. But if she had a serious, spreadable illness that she had not recovered from, I would not want her to take the risk of coming to an event with a ton of people. The sister in this story cares more about her party than her sister's health, her own, or her guests', and that is sad to behold.
