Awww, I feel with you Bladedo
As some of you might know, the only grandparent I knew well(grandma of mother's side) died about 1,25 years ago(August 4th 2007), so yeah I know how this feels.
LET ME LOSE AT THE SCHOOL DIRECTORS, LET ME AT THEM!!!
What I was trying to say is, try to convince the directors to let you go to the funeral or ask your parents to talk to them.
Anyways, I feel with you man
