in some occasion, you should use right hand........
like having a famliy dinner in a round table where there are not
much space between every sit, if the person on your left is using
right hand, and you use left hand, the chance that your arms
pushing each other is very high.
Most toilet flush handles are placed on the right hand side. Most
toilet tissue paper are mount on the right handside from where you
sitting. Most doors handles are meant to be open by right hand too.
In fact, most of the things are designed for right handed
people.
so, if you are left handed, you should try to adapt to it.
