I would like to thank Hashem that we can hold it in!!
Thank you Hashem!!! Imagine if we couldn't hold it in? If it just came out randomly and unexpectedly. The entire street would be one big, disgusting, filthy bathroom. We could never learn Torah in a Beis Medrash because at any minute people would be going. The whole world would be filthy. We go on an airplane and there is urine and feces everywhere. We go to work and there is urine and feces everywhere. Our bedroom is constantly being sullied with smelly yellow liquid and dark brown solid mass. YICCCCCHHHHHH!!! Everywhere. We wake up in the morning and we find ourselves full of .... Unbearable.
You are on a date - and right in the middle s/he/you go. Right there.
So Hashem did us a HUUUUUGE chesed and gave us the capacity [from about age 2 with some help from Mommy] to hold it in and release it [to our great relief!!] at the right time in the right place. [And THANK YOU HASHEM for a plumbing system. And THANK YOU Arab workers for installing it:-)].
Ever think of that? הודו לה' כי טוב כי לעולם חסדו!!
Another holding it in: People can hold in their thoughts and not just blurt out whatever they think. THANK G-D!! Imagine everybody would know what we are thinking at all times? EMBARRASSING!!! Imagine we would know what other people think of us?! We wouldn't want to know....
So thank you Hashem for the ability to keep our thoughts private.
