My clever sister and unsuspecting dad

My sister had maths exam the next day and wanted dad to come early so he could tutor her for the exam.

My dad was busy in an office meeting.

She called him from her cell phone.

No answer.

From mine and mother’s cell phone.

No answer.

From the land line.

No answer.

 She went to my grandma’s room. She stealthily picked up her phone while she was reading a religious book and called my dad.

Seeing my grandma’s number on cell phone my dad picked it up at the first ring and said anxiously, “Yes amma?” She knew my dad would yield only to gandma.

My sister imitated my grandma’s voice and said,” Come fast son! I can't find my diabetes tablets.”

My father sensing mischief laughed heartily in the middle of the meeting. He concluded it early and arrived home.
