I’m suspect of girls who post a picture of their cat as their Facebook profile picture. There are two possibilities for this oddness that take favor over all others:
1.) The girl is hideous to behold and is polite enough to spare others on the interweb her Quasimodoness.
2.) She quite overtly wants to be a cat. So either she has no confidence in herself as a human or she has desires to crap in a box under the sink.
