my friend moe

so i was on the phone with my friend moe the other day, when the battery started to die. i went upstairs to get the charger, then proceeded to think of something else i needed.
i got back downstairs and told moe, 'ugh. i just went upstairs to get the charger for my phone and guess what i forgot up there.'
moe: 'um...your phone?'
me: 'my phone?'
moe: 'yeah, you forgot your phone.'
me: 'really? my phone? i forgot my phone upstairs?'
moe: 'yeah!'
me: 'um, sweetie? then how am i talking to you?'
moe: 'oh.'
