Yesterday It Was Whys But Today It Is IF! why?

If I start answering to many questions today I won't get very much else done! If I saw someone answering my question asking me to email them and leaving a phone # I wouldn't there's no if and or buts! If I saw something like that it would be very strange!!! Then I'd have to ask myself why again!I If that person was a pervert and I made contact what then? If my sons friend called and said he was coming over just to phone back saying he can't because his other friend is coming over to his house that's no friend so as you can see what if's can drive you crazy!! Only if you know what I mean!!
