Pooping in pants HELP?

what do other ppl do when they poop in there pants and your not home. like if you are in a store gettin grocerys with ur mom or sitting in class. at home i just take them off sometimes i just clean them in the sink fast or if i hav to i throw them away or bury them in the ground. i never pooped in class but i get scared thinking it could happen 1 day. when i am in a store i just go to the bathrrom fast and throw my underwear in the trash can and no 1 nos. 1 time i had diareeah and i had to keep walkng with my mom in the store i couldnt do anything about it i thought i was going to leave a trail behind me as i walk but i tucked my pants into my socks. that was the worst time ever. rlly embarresing, it doesnt happen a lot maybe once a month sometimes i think there is something wrong with me or my parents took to long to potty train me but i no even some grownups wear diapers so i feel better. but what do you guys do with all your pants and underwear. my dad is starting to ask questions and wonder what happends to all of my pants he buys and tells me he doesnt work 40 hours a week so he can spend it all on pants for me. i just tell him idk where they go. he thinks i sell them to kids at school so i can buy snacks at lunch. so what do u ppl do with your pants do u just wash them real good or bring them to a dry cleaner or something? i need to no!!!!
