Which is absolutely nothing for some people. Fifty texts may seem a lot to some individuals, but its very realistic for others and fifty a day would actually seem low. You have to remember, that if someone texts you, and you text them back, that's two texts right there. Say you text to seven people per day, that's only a little under eight messages per day per person.
Anyways the situation is simple. Get them off your phone and put them wherever or print them out.
