      My group of friends use discord for all of our communication and in this server a certain friend (L) wanted to have a sleepover to record some games with us. 

     Me and another friend (C) we’re at a gaming tournament and C didn’t have a phone that could use discord. 
     
     Earlier in the day L had said that C and I should “just come over ASAP.” I told him that we would be late since the tournament ended at 7PM. At 6:30 L sent a message notifying us: “@everyone sleepover my place” this message popped up on my phones home screen so I could see it easily

     
     At 6:37 another friend said that he couldn’t go. At 6:42 L said “sick no sleepover actually”
He sent this message without @‘ing anyone and I didn’t see it.

     C and I left the tournament at about 7:15 PM, dropped a friend off at home and went to L’s house. His sister opened the door and let us in. She said that “L is upstairs in his room.” On our way upstairs, L’s mom said that he had just left and that he would be home probably in an hour. So C and I spent an hour in L’s room playing games while he was out. 

     At 8:40 L’s mom said we might just want to leave and that L told her to kick us out. He said to me “I told y’all not to come ya know.”

     I believe that he should’ve @‘ed us to notify me that it was cancelled and that it was reasonable to expect that I wouldn’t see a message I wasn’t notified for. 

    He and others think that I should’ve seen the message and not just arrived at his house. He says that he did notify us but I just didn’t look
