<human>: At a recent family gathering held at my husband's grandparent's house, we were engaging in pizza eating activities in the Den/Bonus room (couch, tv, etc.). So a distant cousin (female) is with her 1 year old, and hands him an entire slice of pizza! Better yet, the kid is sitting on the floor where there is a dark colored carpet, and an angry, long haired, shedding chihuahua. So the kid proceeds to bang the pizza on the floor, take a bite, rub pizza on floor, be a giddy 1 year old and giggle, take a bite.
NOTE: After a few floor banging sessions there was very obvious dog hair on said pizza. He continues to eat pizza.
I ask child's mother if he needs a plate or something and she says "he won't use it anyway". Oooookay. Continue to sit next to my husband and my my own damn business. 
Child gets to about crust level on pizza (still sauce) and begins to bang/rub pizza all over our pants and legs. Did not rub pizza on his Mother's pants or legs. Makes a huge mess. Really annoys us. Mother looks over and laughs and continues enjoying pizza. Parent of the year?

Can you provide a brief overview of the text?
<bot>: Mother gives a 1 year old an entire slice of pizza. Kid rubs it all over floor, all over my pants, child's mother laughs.
