When I was a child and a teen it was always 4 or any combination that added to or half of four. Could have even been 4 4's. Could have been 2, which is half of four. For some reason I hated 5.

But I can also tell you I have or have had fears of certain numbers. The number 95 scares me for some reason. If I am giving someone an example of a percentage, and if I accidently say 95, I fear something bad might happen.

85 also scares me, but not as much as it used to. Some of the year 1985 was not a great year for me.

Hope this explains some of my fears or safe numbers.
