Angel ... yeah ... just this morning Jesse started running & ran straight into the glass window/sliding door .... massive bang, gave him a big fright the poor thing ... cried his eyes out so much he could hardly catch his breath ... he was alright tho just a nice bump on his forehead .... think he actually fell cause he lost his footing, the steps are so quick you don't have time to say "hey slow down" ...
