<human>: Can you provide a brief rundown of the text in within 3 sentences?

I was at the mall with my girlfriend carrying bags and giving her my assurance that I think she looks good  in the clothes she's picking out (which apparently means nothing). We then bump into her friends and I take this as my opportunity to go to subway and get a sandwhich since I've worked up quite the appetite. As I finish my sandwhich and reach for the free cookie they gave me, I get a call from my girlfriend saying that she's finished shopping and needs help with the bags, so I decided to leave the cookie in my shirt pocket and eat it on the way home.

This was on  Monday. Yesterday was laundry day, and now my clothes smell of cookies and it took forever to get all the crumbs out.
<bot>: left a cookie in my shirt pocket before laundry day making my clothes smell like cookies and leaving crumbs all over them.
