I have a half-sister who is 15 years younger than me (I'm in my mid-40s). She is single. Whenever she visits, she rarely lifts a finger to help out around the house. I'm wondering if this is common: do people with single younger siblings wind up just doing all the cooking/clean up/etc.? I have a husband who works ridiculously long hours, so I'm already pulling most of the load around the house, and we have a preschooler, so that makes two people I wind up looking after. When my sister visits, it would be nice to get a bit of a helping hand, but instead I just get a third person to clean up after and cook for. It upsets me because I can't understand why it doesn't occur to her to help out a bit. Just by way of an example, today I cleaned up the kitchen three times, cooked breakfast, lunch, dinner, made coffee and tea, set the table, cleared the table, loaded/unloaded the dishwasher, cleared up multiple projects of DC's (thanks to the snow day), did laundry, and some other routine things. I went upstairs to put DC to bed after dinner (DH was out) and when I came down half an hour later, she was parked in a chair sipping wine and working her phone while the dirty dinner dishes were still on the table and the kitchen was a mess from when I made dinner. I just don't get this because when I was her age, when I visited family or anyone else I was interested in lending a hand and helping out, not just parking on my butt and letting other people do all the work. In her shoes, how does she not think of at least clearing the dinner table and bringing stuff into the kitchen and putting it on the counter? FWIW, she is not somebody with a full-time job and therefore needs to be in "vacation mode" when she visits. I know people will say that I should just ask her for help or assign her duties, but the problem is that it upsets me that she doesn't have the empathy towards me to think of helping me out without me having to assign her tasks. She knows the dinner plates are dirty. She knows I spent 40 minutes cooking dinner. She knows the table has to be cleared and the kitchen cleaned up. Why can't it occur to her to want to help me out?

Anyway, thanks for letting me vent.
