texting,and all that......

so he texts me at 6.15am this morning,a jokey text that I didnt understand at first cos I have a baaaaaaad memory when drunk,not drunk at that time btw,I'm talking the night before,so I nearly deleted it because I didnt recognise the number and thought it was one of those texts that want you to reply then charge you a tenner a minute or something!! Anyway,why do men text?I never do,I always phone them,I think its a cop out!!!
