Me: “...Hello?”
Him: “Hi! Are you okay?”
Me: “yeah I’m fine.”
Him: “I’m on my way!”
Me: “what?! Where?”
Him: “to your workplace”
Me: “what the hell?!” (we haven’t talked in weeks and I’m at home)
Him: “ohhhh shit! Whoops… i've phoned the wrong number. I didn’t mean to call you!”
Me: “Right… Okay bye”
Him: “Sorry! How are you anyway?”
