Hi! If you are still interested in spending time with this person, but amusement parks aren't your "cup of tea," do kindly tell them, but have another plan to fill the void! Amusement parks are outside, so I'm gathering you like to be outside (very nice.) As corny as it sounds, go to the zoo. This is outside entertainment, or look to see if there is a jazz concert around, grab a back pack put an old table cloth or blanket, french bread, a white cheese, some fruit, & white wine, & go to a free outdoor concert! This way they won't feel like you are giving them "the brush off.".. and You'll be honest! have fun!
well first of all do not lie because that means u dont have honesty, well getting to your question i recomend to tell your friend that u dont wanna go and if she is ur bff she will understand also you can give her reasons why not and even u can also say perhaps some other time this will be showing manners and that u deserve some time without her
