I know all euphemisms are just dancing around bullshit, but this particular one bothers me:

"live at home"

We all know it means that you are living with your parents. Clearly you are ashamed to say that, but you don't want to admit that. Give any reason you want for why, the fact remains that you are trying to hide this fact.

I know there are valid reasons for having to live with your parents. But when you try and conceal that detail, it tells me you do not have a good reason.
