Sometime it is not people feel shy. Just feel uncomfortable.
Some parents like to look at their future
son-in-law/daughter-in-law throughly, look from head to toe, look
back from toe to head. Still not enough want to see somemore, look
from right shoulder to left shoulder, look back from left shoulder
to right shoulder etc etc.

When i look at you, i was afraid 2 talk 2 you.
When i talk 2 you, i was afraid 2 hold you.
When i hold you, i was afraid 2 love you.
Now that i have loved you, i am afraid 2 lose you.
