Mobile phones don't keep you punctual. Watches do. I needn't bother with a watch since I have a mobile phone, which is a typical reaction from age by the people who are presently blaming the harmful impacts of mobile phone use. Looking for mobile phones always to check time looks fishy and desperate. A speedy look towards your wrist is a lot more tasteful approach to watch time during a date or a gathering. Also how inconsiderate it would appear to your friends if you pulled out your mobile phone during a discussion.
