I was up all night with a sick friend spoken language informal
A common excuse for not being where one was meant to be the night before.
Mom: Where was you last night ? Son: I was up all night with a sick friend.
I didn't go home last night. I'm afraid my mom would be furious at me, but she's calmed down after hearing my reason, "I was up all night with a sick friend".
Although I said "I was up all night with a sick friend", my dad didn't trust in me.
