OP, don’t listen to the absolute idiots on this thread who say “it’s time to move out” “go to a house share” “you’re too old to live with parents”. Because the majority of these people will already have their own homes, mortgages and husbands.
They have no idea what it’s like to save for a house as a young single person.
Renting and house shares are a complete waste of money if you’re in the lucky situation with living with parents in order to save.
Your parents are obviously happy for you to live with them until you can save enough. Most good parents would want that for their children.
They may see you as lazy if they are the ones doing all the house work and cooking. If you sit back and let them do it with the expectation of “oh my mum always cooks so there’s no point me doing it” I can see why they would be annoyed and snap.
Don’t expect an apology. Just let it go. As others have said, be a bit more proactive and take charge. If you all share a wash basket, get up early one Sunday morning and take the whole basket and do the washing. Go to the supermarket after work and grab a food shop for everyone. On an evening when everyone has finished their meals, do the washing up and give the kitchen a full deep clean. They will start to appreciate it and you.
When you do get your own place you’ll be able to get into a routine easier than if you’ve spent a few years never making your own meals or doing your own laundry. You’ll feel, ironically, more independent.
Go and make conversation with them, have a drink and enjoy your New Years!
