Junkie1 and Junkie2 are going camping
1: Bro, its getting dark, we need to light some torches and put them on the trees
2: ok! (gets coal from grill and a stick)
1: no wait i already have some! (gets matches)
2: wait what we thinking! putting torches on trees is just as bad as flint and iron!
1: well if we cant have light, we have to stay up all night and make sure creepers don't get us.
2: we can still make a small fort with the wood around us (punches trees)
1: (comes to senses) oh no! we have minecraft sickness!
