Do you think this is fair?

This morning my mom took my makeup away from me because I didn't clean it up after she asked me too so that made me mad so I put my barefeet on the kitchen table my mom just cleaned to make her mad and then I yelled hey mom how clean does the table look now and I was wiggling my toes trying to be funny so she walked over grabbed me up and walked me into my bedroom and said get comfortable because you are going to be here a while because your grounded for a week. I don't think that's fair I think that is too harsh it's just barefeet so what she should have just thought it was funny. Who would have known putting barefeet on the table would get ya grounded. Do you think it's fair?
