     Talking on a mobile phone is expensive, so a lot of people send text messages. Text messages are
much cheaper by making the words shorter. You can do this by taking out "unimportant" letters in the
words and using numbers instead of words (2=to, 3=free, 4 = for, 8 = ate, so, etc. ). You can also keep
a way from using punctuation. Here is an example: Do u wnt 2 g 2 th cnma tnit? (Do you want go to the
cinema tonight?)
     What do you think these text messages mean?
     Whr hv U bn? Iv bn wing hrs fr a cll.
     Im hm nw, why nt gv me a cll.
     I gt a txt mssge frm my frnd. Shes hvng a prty on Strdy.
     Mobile phone users have developed a group of symbols to show how they feel. They are called
emoticons, and there are some examples below. To read an emoticon, you have to look at it sideways.

     Why didt you call me? I'm so sad.- (Here are some others. Can you think of text messages where
