Tasha, you don't look like a biter to me. You must have been provoked to bite someone but make every effort to never do it again unless it is necessary to protect your GrandPa. I am thankful that your GrandPa took you over when others were willing to let you go down the pike. It appears to me that GrandPa is a fine man and I think that you and he are quite a team. I wish a bright future and much happiness for you and GrandPa.
