Many a time people waiting by the phone.
Be it waiting for a call from a love one, anticipate appointments or simply hoping someone would call.
Picking up the phone 'n make a random call feels like forever.
Maybe the call charges is high or simply feeling shy to do so.
More true in our modern society where it places importance on phone calls 'n the value of people's time.
SMS is an option. Depends on a person, sms can be a tool to lay down messages, requesting a quick response or a simple gesture of goodwill.
Whatever it is, the cellphone can become handy as you carry it with you wherever you are.
Feel bless for this modern commodity 'n take great care of them.
On the other hand, there are cellphones that ring incessantly.
