Friend is a person who is not an enemy or who is in the same side. Best friend is someone that you can be completely honest with. You can be yourself around that person and that person can be themself around you and shares the strongest possible kind of friendship.To me, Tha is my best friend.She always explains the thing that I don't understand to me but sometimes she explain me the wrong thing but that's ok because there's no one who knows everything in this world.she loves biology ver much.I loves Physics,Math.She helps me with biology and i helps her with Math and Physics and sometimes when i absent or sick she always keep the worksheets for me.That's why Tha is my best friend
