Fish Feeder
There are some people out there who lie for absolutely no reason whatsoever, and they are known as compulsive liars. This friend appears to be one of those people – why did he pretend he would feed the fish if he never had any intention of actually doing so in the first place?!
Did the friend just think that the user would forget about it? Or did he assume that the fish would survive for two weeks without being fed? Technically, this is a form of employing somebody, so the user could report the friend to the police for fraud. I know I would!
