im grounded

my mom went to the airport to pick up my dad and i asked her if i could walk to dunkin donuts to get a donut while she was gone she said no and told me to not leave the house i ended up getting away with it until i was hanging with my friend and we left to go walk to sonic cause we was hungry and she wen through my room and found a donut and now im grounded for a week i cant have friends over and i have to come straight home right after school. it doesnt sound like too bad of a punishment but for me it is now i have to cancel a bunch of plans
