Sometimes when numbers are considered natural to each other, they still can be miles apart when looking for common denominators. Thus, the 7 and 5. What they can enjoy is a one on one conversation.
Though the 5 loves to interact with others, the 7 would much prefer the one on one party. Thus, catching up with friends (just the two of you) is a good idea on this Friday.
These two might do well in business, except for the money issue - should we keep it? Should we spend it? Do we need it? It's a wild card for the 7 when it comes to finances, and 5 will spend money out the wazoo. So watch the bank account today. Spending to emotionally feel better may not be in anyone's best interest.
What we can say about the 7/5 combo is that change is in the air - should you want it. 7 says, "Do a little research before you take the final leap." Do your homework first. It doesn't have to be an all day venture or turn into a research project. But with the spontaneity of the 5, it's always nice to have one number urge us to slow down and see what we're getting into first.
