What we did/learned today







































sorry I couldn't find a video relating to what we learned today but leave comments if i am wrong, wasn't suppose to do something, etc.

Jomel's Pay it Forward

Part 2:

Donating winter clothes to salvation army. I choose this activity because I thought donating winter clothing to a charity would probably help a kid in need of a jacket, scarf, etc. I do not know who I help but I'm guessing I helped someone in need of warm clothing during the winter. What I did was, I got old pieces of clothing that were not useful anymore and put them in a bag so I could bring them to Salvation Army. Today November 16, 2011 around 4:00pm

Part 3:

My act of kindness went pretty well since it was an easy task. I asked the cashier if I was able to donate clothing and she said "yes, all you have to do is put it in the bin" so i got the clothes from my dad's car and brought it to the bin. I felt happy for what I have done because i know that someone else would be enjoying the winter clothing and be warm in it too! Well... the cashier thought it was a very nice thing and said thanks. I told the cashier this is for my pay it forward project. The cashier was thankful for the donation of clothing.

Part 4:

I think it is important because helping people in the world can make a difference to you and others. I'm not sure that my act of kindness has made a difference but it soon could make a difference for someone in need of winter clothing.
