If at times you find going out and socialising a bit of a choir, spare a thought for people who suffer with a stammer. Stammering is a much wider problem than many people care to imagine and the affects of having a stammer can be very damaging.
Most people who stammer would love to have the confidence and overall fluency to speak much more than they actually do in reality. Take for example a social situation where the person who has the speech impediment has been invited to the local pub to spend a Friday night out with his friends. Firstly if this evening has been planned for a number of days the stammerer will more than likely have been worrying about this night for some time, possibly even losing out on some important sleep. This is because people who stammer can at times find it quite difficult to socialise.
During the evening itself one his/her friends may ask him/her, how their week has been. The person who has the stammer has plenty that they would like to say and may have some very interesting news/stories to tell, but more often than not will simply reply with a one word answer such as OK. This can make the stammerer look like quite a dim, boring or shy...
