Huh... odd... I see you @ed me, but I don't recall ever getting the notification that you did.
Indeed I do like phone conversations myself. I basically have two VERY good friends that I somewhat regularly call. One is a fellow mod on here. We're close enough that we actually do video calling as I've known him for like 7 years now. Another, is a really good friend I've known for almost 6 years now. I don't mind video calling him either, but most of the time he likes to stick with phone calls due to limited data on his phone. There is a few other friends that I do calls with every once in awhile, but it's not often.
However, most of the time I generally do stick to PM or IM. Even though, in truth, I like voice conversations more.
