1. See what kind of person you are and how to refuse, and don't have any fear.
Find a substantive reason to refuse, so that others will not embarrass you.
3. If you are a close friend, you can complain occasionally, just tell her that you don't want to go, just say that you don't want to go, I'm tired, I'm busy and don't want to move. Say what you think is good for you anyway. If you are not familiar with it, it will be easier!
4. You can honestly refuse others, say that you don't want to talk about it, and of course change yourself (say it obediently), so that others will think that you are honest and won't make excuses like others. After that, there is nothing to find you in the future.
Note: Be tough when you refuse others. If you procrastinate, others will think you are easy to talk to and treat you as a post-it note. This is not a good way to communicate with others. Being smart is also good for you, and you can protect yourself well. This doesn't mean that you should do any calculations. This is the case with Founder Society. Be gentle, make a little joke once in a while and run errands is enough.
