7. Cancer
How well can you get a long with a Cancer? Spin the wheel and find out! These folks are well-known for being moody and can often switch from nice-as-pie to super-nasty depending on the day. At times they can be exhausting due to all the flip-flopping, but they can be quite good at smoothing things over with nearly endless compliments when they are feeling the love. On other days, it might be best to just leave them alone.
