Some people get used to free services
They can be your friends or your acquaintances.
When you are too kind and helpful.
These fools think you will be there doing that forever.
When comes that one day you can't help them,
They will tell you:" You are never there" and ****...
I call them "favour abusers".
Pay attention, this is common when you are too utile.
Remember that your time is precious, you are not obligated to respond to their demands.
Or feel guilty to not have time.
Plus it is for free !!!
