(this is what my lack of ideas does to me)

You started going to school recently since you studied at home (Luther was the one who taught you) but as Randal went to school you also wanted to go but you were in a lower grade than him (considering your age) but even so when class ended he would pick you up and you two would go home together

So today was a little different...? he just picked you up and had a bike(he probably didn't even know how to ride one) while still smiling like a maniac like always, how did he get that bike? It was probably due to one of his (crazy) "methods"

He calls you while still smiling while in one hand he holds the handlebars of the bike smiling "Look what I found! You can sit down now and I carry you on the bike." He says with a maniacal smile probably like a strange idea he didn't even know how to ride that bike probably imagine how he came to you with it
