How do you say no to friends who ask you to help carry things when you are traveling?

Everyone will go on a trip, and as soon as you say you are going on a trip, others will ask you to bring something. Well, if you refuse directly on the surface, your friends will think that you don’t take me seriously at all. Friends, so we should be more tactful when rejecting friends. If we have too many things, we can directly tell our friends that I brought too many things and there is no way to bring them back. If you can, you can still say, if there is something good If you have something, you will bring it back. If it is not good, you don’t need to bring it back. Such a tactful rejection, rather than a direct rejection, will affect the relationship between the two people.
