I’ve been pondering partnerships lately and it is interesting to note that although the roles of partners are different (they compliment each other). One person usually carries one burden and the other person carries another, both equal weights, but it is usually in their capacity or strengths. Thus many men go off and work while their partner (wife) stays home with the kids and cleans house, etc. now, both feel the weight from time to time, but it is important for each to do their part and to value the other for their part. Below is my short study on partners.
It is a partnership in which partners share equally in both responsibility and liability.
A partner is:
A friend who shares a common interest or participates in achieving a common goal
A sexual partner
A significant other in an intimate relationship
Wife or husband in a family
A member of a partnership
A business partner
Partner (business rank), a member of a law firm or accounting firm which is formed as a partnership
A participant in a partner dance
A participant in a game with teams of two, such as tennis doubles, contract bridge, or Partners (board game).
