No, it definitely does not make you a loser. She is just being a bitch. IMHO the ages she quotes is kinda young. I am now 33 and just bought a home, gotta wait for it to finishing getting built though, and it's my first. I wanted to make sure I was ready before I took on the responsibility.
Now on the other hand, if your 22 and still living with your parents, then THAT qualifies you as a loser.
Just tell her to go fuck herself.
