In the past, no matter what time of the year I remember I can get in the shower and enjoy a hot, steamy relaxation.

As of the last month, it seems like anytime I get in the shower its cold... and Im left standing there trying to get warm?!? Around the time Im done applying soap and shampoo on myself...the water than begins to feel warmer. (Im already done!!!) Its probably a few hours before anybody used the hot water, so I dont think that could be the problem. My parents wake up at 5am... and shower around 6. Im getting up around 9-10am.

Can anybody explain this prob?
