when i was about four or five, i learned the magic of a hot glue gun. how did that weird stick suddenly turn to goo? sadly, it sorta took a tangible lesson to learn the where the "hot" came in for "hot glue gun." let's just say it resulted in my touching the hot gooey substance and a very painful index finger.
i somehow did not manage to believe my dad when he said that the glue would just come off easily once it dried. now i don't know what exactly proceeded the touching, but the final result was not simply a little burn and a pained finger, but me losing a whole chunk of skin off my finger where the glue once was.
ever since then, almost every encounter i've had with a hot glue gun resulted in a burn of some sort, big or small. i was reminded of that today.
