fixing the roof

For a long time Akpos has been battling with a leak in his roof. One night there was a very heavy down pour, he had to move from one corner of his house to the other to avoid drops from his roof. This made him have sleepless night. The next morning he decided to fix his roof, after scouting for ladder in his neighborhood, he tried to climb to the roof. Climbing wasn't easy, he panted and sweated but successfully climbed to the roof, as he was about to fix the damage, he heard a knock on his door. He yelled from the top of his voice; "who is that?"HIS friend Biodun showed up at the ground and said, "excuse me, can I see u?" Akpos asked "what is it you want to tell me?" Biodun said,"just spare me one minute". Akpos climbed back to the ground, looking tired and asked "what can I do for you?" biodun said "can u give me N50?" Akpos thought for a while and said "FOLLOW ME". The two of them started climbing to the roof, panting and gasping for breath, they got to the roof, after panting for one minute Akpos turned to the biodun and said "I DON'T HAVE" ONE WORD FOR AKPOS
