stubborn and unyielding

i've found out recently i'm quite stubborn and inflexible. i refuse to get up at 8am on a saturday, my day off, to go to the home design show... 8am... even if i do wake up at 8am, it doesn't mean i'm ready to move out of bed and to be up and ready to go... so.. i'm sorry, if i seem like an unyielding and inflexible friend, but sometimes, scheduling just doesn't work out. so.... knowing how annoyed you might feel, i feel YOU should be flexible in your temperament and just chill and realize it's okay if we can't go together.
