To my friend,I can bear,no matter how many times.Because they are my friends.And sometimes i will use some small methods to avoid the situation.If we reserve the time at 12:00,we will tell the one among us who always stands us up that the time of appointment is 11:30 or much earlier.
When others can not initiative to change their habits like be late or stand others up,we should give them a lesson.We should let these guys know we may be not mind to wait for a moment, but we should be respected,if we are friends .
