user: How Many Players are there in a Football Team?

assistant: Two teams of eleven (11) players are usually involved in a typical game of regulation football. It is worth noting that a variety of player formations get used in different competitions. For example, there are some variances in Premiership, League and in European matches.

In 11-a-side games, there must be at least seven (7) players. The rules allow for three (3) substitutes from the 7 available. But, their names must get nominated before the game begins.

user: What should I do if I disagree with a friend, co-worker or family member on something I feel passionate about, such as politics?

assistant: Seeing things differently from someone you interact with regularly or even care about can be a hard thing to experience. It can also a wonderful thing. Each person on this planet is different and their beliefs are based on their culture, upbringing, personal experiences, education, surroundings, etc. Recognizing this and truly listening to the other persons perspective is important. In many cases, when a difference of opinion escalates, it is because one or both people involved did not listen or respect the other. If you are being close-minded, then you could be missing out on learning something new.
If both parties still disagree and it is not something completely against your beliefs, culture, or ethics, that is OK too. Agree to disagree and move on. Life is too short to be angry at people you care about just because you do not see eye to eye.
