Could be off topic but what's wrong in living with parents ? After all, we are from India and it's quite normal in here to live with parents.
In fact, some people live in a joint family and so even if we have lots of money, I don't think living with parents is something wrong ?
As a standalone basically nothing is wrong with it. However, in context it made sense for the friend group as they already knew I had been looking forward to moving and that supposed level of money would have more than afforded it.
