Is it normal for me to warn my older sister?
i had an older sister and because of covid-19 she stayed at home while she usually stayed on a boarding house.
I dislike her presence because she like to stay up late until midnight and being noisy. like calling her friends, playing games and laughing like mad, or other stuff.
i am around 20 years old and some of my friends told me that it is normal. just brush it off. but i don't think so, i feel like if she is being noisy and disturb me, i should told her. yeah, sometimes i used my earplug and just go to sleep. but using earplug is uncomfortable.
so is it actually makes sense for me to told her to shut up?
