<human>: TIFU real bad. First I have to tell you that I am from Austria, so please forgive me possible typos and grammar mistakes. Second, I live in a very small town (really teeny-weeny) so when I do the groceries I go to the same teeny-weeny store everytime, because I bet you can imagine why- we only have that one.
So long story short- I can never show my face there again.
This is how my story starts: it really was (unlike most of the other stories) today, when I decided to treat my two nasty pimples (one on my forehead, the other one on my chin) like I treat them always when they don't want to go away. I put some toothpaste on them fuckers! 
I did that around 3pm. So when it was like 5pm I kissed my boyfriend goodbye and went to the store. There I bought everything I needed and went to pay. Since I know the cashier I chatted a little bit. You know just how everything's going. Everything was like usual, nothing special.
So then I said thank you and goodbye like the nice girl I am and went home. You have to know I'm very neat and tidy so first thing I got home I went to wash my hands. 
And as I looked into the mirror I nearly fainted. I had strange white spots all over my face. In that moment I realized that I hadn't washed off the toothpaste before going out of the house. I looked like I had the plaque or some sort of scabies. And then it came to my mind that I talked to the cashier for almost 5 minutes. I really don't want to know what she must have thought of me.
And the very best of it: not even my bf told me how I look when he kissed me goodbye. Afterwards he claimed he didn't see it either.
So the conclusion is I feel so embarrassed that from now on I'm going to send my bf to go buy the groceries, I'm not going there again.

Can you condense the text into three sentences or less?
<bot>: Went to the store with toothpaste on my face to cure my pimples, because I forgot to wash it off.
