When you rent an apartment, all the landlord truly cares about is, (1) will you be able to pay the rent, (2) are you going to trash the apartment, and (3) are you going to turn the dining room into a meth-lab. So if the landlord has even a walnut sized brain, before they lease the apartment to you, they run credit and criminal background checks on you. If all checks out, you get the apartment.
The landlord does not care if you are pretty.
When you meet a woman and start thinking about moving from a non-serious relationship into a serious one, all you tend to automatically care about is whether or not she is pretty.
