Alec went out and scrubbed five windows, starting in the back and working his way around. His work was good... where he could reach. Even with a small step stool - he didn't want to try a ladder - there was still a small section at the top of the window that he could not reach no matter how hard he stretched.
Xander came out after a while, curious about where his brother had gotten off to, and watched him. He watched for two windows before saying, "You know you're missing a spot, right?"
"Something's better than nothing when it comes to seeing out a window, and I can't reach it!" Alec grumbled.
"Ladder?" Xander suggested.
"Not without a spotter!"
"Fair. Alright, then, how about another way?"
After a bit of back and forth, Alec got up on Xander's shoulders and sat there grinning like a buffon as he wiped the top part of the windows and scrubbed them clean. Xander was a good ladder or lift or whatever he was called and held Alec steady between walkin back and forth.
