You hate your ex?
No worries. Give a call to her. Ohh, do it at night only. Disconnect the call and call again.
Stop calling in the 3rd attempt. She’ll call you now.
Go for sleep. No no, don’t cut the call. Make it silent. Or keep it in the other room.
You’re giving charity to her mobile company’s bandwidth business. You’re a philanthropist while you sleep. You’re cool.
