A friend asked me to help someone flag for shroud. I was level 17 and planning to run those quests anyhow so I invited him to join us the next day @ 7pm EST.
The next day he didn't show. We wait until 7:45 and finally started. About 11pm he messages me and asks me to join his party. I told him we finished those quests and were getting ready to run shroud.
He acknowledges he was late but said I should have waited and got real mad and logged off. I sent him a mail message to let him know I would run it with him on the weekend. I learned I was squelched.
