(Ok this is gonna start when they were teens! So slenderman is 16 and Zalgo is 17)

Zalgo was sleeping and his mother came in "sweetie wake up please you don't wanna be late for your time with your dad!". Zalgo groans and sits up he didn't like his that much. "Ok mom im getting up so you can leave now". His mom left and he got dressed and went outside and saw his dad and his dad saw him "hey son! You ready for some fun! Lets play catch! I got gloves and the ball!" His father hands him glove and they play for a while his dad threw it to far and as Zalgo goes deeper he soons bumps into slenderman "sorry i didn't see you" slenderman "looks" up at him "its fine!" They talk for awhile then slenderman's dad got in between them and Zalgo's dad also got in between them. Zalgo's dad growls at slenderman's dad "keep your kid away from my kid!" Slenderman's growled "planning on it! Come on child lets go!" Slenderman nodded and they left and when Zalgo and his dad got home his dad was very unhappy.
