Your friend tells you he's coming to Nairobi kufanya shughuli kidogo, you accept to host him for that one day. He wakes up asubuhi kumbe he's going to 'deal' with his 'cheating' girlfriend. You come back from job, you find alishaenda. You text him 'bro ulifika poa?'. He replies

"Ata ndio nimemaliza ile shughuli sai niko kwa gari heading home, asante bro umenisaidia sana". As a caring bro you tell him 'safe journey and take care bro'. After a day the girlfriend is found dead. DCI officers doing their work they find your friend is the main suspect.....

He's arrested, checking his chats you were the last person he talked to during that whole activity. You also become a suspect. Do you think thru your communications it will be an easy thing? Your name will be mentioned everywhere... Anyway, what do you learn from this? Nimeenda!
