awkward MPD moments

So I just called a supporter, hoping to ask them if they would be willing to coordinate a group MPD appointment by inviting people from her church that she thinks would be interested as well as setting up the event etc. Unfortunately she was not there so I left a message. For those of you who have experienced a voicemail message from me will know that I suck at them. This one was not long-winded, but just.... awkward:

"Hi Esther, this is JW and I'm calling with a favour or proposition to ask of you...." I pause and think of the meaning of 'to proposition someone' and then laugh and correct myself, "Er.. not a proposition, that's awkward. Anyways, ___ is my number and I'll try again another time." As I hung up the phone I was beet red. I looked up the meaning of "proposition" to find that it does have multiple meanings; my instincts were right and in correcting myself I had made a bigger fool of myself than had I just left it. Awesome. I knew I should have stuck to the script.
