Why?

Why do they call my name when I am super busy?  I can't do anything without someone yelling, "Mom, come here!"  Yes, they expect me to drop whatever I am doing and run to them or they get mad.  Then I get punished by them for at least a day or two.  I can be in the shower, washing dishes or have just sat down exhausted from running all day and they yell for me.  My thing is - if you are bleeding call 911, not me.  If it is something that can wait - give me a minute.  If it is something I must see - take a picture of it.  If I yell for them to come running right now, they laugh and most of the time I have to wait.  I have been in some predicaments and yelled and had to suffer before they came, certainly not running.  Come on, I want someone to run at my beck and call too.  Can I hire a slave?.....
