not everybody's the same

I found myself facing that we are all different all throughout this week. In this class I realized that what seems to be an acceptable amount of money to spend is not acceptable to others, how much time and effort to spend on creating our own e-commerce presence also differs from person to person.
In one my classes this semester my group seemed to work together really well. We are all on East Coast time, all fathers, and all about the same age. In another group the members are from all over the place and different ages and gender. The teacher paid no attention to our wishes and simply force assigned us. I find myself with group members that love to talk, quickly get off topic, all want to chime in on every question, and one of them is extremely hard to understand.
I am not the most patient person and it is easy for me to become irritated. It's mostly when I feel that people are ignorant, not courteous and respectful towards others, and feel the world revolves around them.
This week I am reminded that just like I expect others to be kind and value other people's time, I need to be respectful of other people's values and their lack of sensibility towards my time.
