See this is where "old" me thinks it does completely reflect on how good of a parent you are. If you are prepared to get into the absolute states she so obviously does (and remembering this is only the bits she chooses to share), then you are putting yourself in harms way. Literally anything could happen to her because she has no concept of who, what or where she is due to her extremely intoxicated state.
Now if something, anything terrible was to happen to her (and sadly things regularly do) where does that leave poor Marliya?
There comes a point in life where you have to grow up, consider the potential consequences of your actions and other people around you.
She's getting drunk like a 15 year old in a park who's never been around alcohol and has to be carried home by their mates with sick in their hair. No Mia, this isn't cool at all. Grow up ffs.
