A persob who likes to keep others, infact everything in control is called as a control freak!
It really depends on the kind of friend he or she is like if she/he likes to hear your voice and has comfort to listening to you talk then call it. If she/he likes reading and likes to hold on to what you say then write her. It also depends on how far away she live if she/he live close then write her it will get to her faster. If he/she live far away and don't see them often enough call them. Hope this helps.
you call the first person you wanted to call and then press flash and then called the second person and then press another flash and there you go , a three way call.
