Two people I know well

I going to describe two great friends, Alex and Ismael.
Alex is fiveteen. He's tall, he's got dark hair and brown eyes. He's very funny and lazy. The best thing about his is, very funny and some times is talling jokes. The worst best about him is, very lazy and some times forget a lot of things.
Ismael is fivveteen too. He's tall than me, he's got short dark hair and dark brown eyes. He's diferent than Alex. He's hard-working and funny too. The best thing about he is, har-working and generous. The worst thing about he is, he make a lot of jokes.
