This mistress did not like the fact that her boyfriend said some mean things to him and yet he wanted her to take him a burger on her way home. She got pissed at what he said and when she got home, she did not give him the burger. She let him see it and then she went outside and she crushed it with her sneakers and made it muddy.
This mistress had bought these sneakers so as to use them to crush things. So she crushed a burger on mud so as to check how durable they were. She wanted ones that could last as long as possible so she walked on mud after she was done crushing the burger and she loved the fact that the sneakers held out as well as she had hoped them to do.
