i lied to my client

today i told my client that the meeting was at 2 pm when it was really supposed to be at 3 pm. idk why i did it, maybe i was trying to get a head start on work or maybe i just wanted to feel less rushed later. now im worried theyll think im unprofessional or unreliable. but honestly, theyre already pretty laid back so hopefully its no big deal. im telling myself its okay because we all make mistakes and its not like it ruined anything big. still though, i kinda hate lying even for small stuff.
