Money Depleting?

As you all should know that i have quitted my job and currently wandering around the streets of S'pore with my Kaki( gang) searching for clothes or anything that interest us. And the most frustrating problem is my EZ-Link card, my student fare have been changed into adult fare! Each time i tap in i must have the habit to tap out, cause i last time always never tap out but will not minus money cause i student fare but now adult fare i must tap out or else penalty minus $2. Waa! To my knowledge, every one or two days i will have to ask my mum for money to top up my EZ-Link card. And i have already calculated, just in 4 days i have top up $20 and now in my EZ-Link card the balance is $-0.23 Argh!! So this few days i will have to quarantine myself from going out to save bus fare and expenses from all the food temptations out there Haha.
