Hey Unc,
It’s really nice here, it’s cold, beautiful and there are SEALS!! They are so cute... they bop up to my sliding door, and then they leave as quickly as they arrived... I built a snowman outside, I named him after your lizard, Jacque, we also had snow cones. They were great! We just have to step outside, grab some snow and BOOM!! Snow cones, I went to the city last week, it was sooooo... cool! But freezing cold hehe... welp! Bye bye Uncy
Yours sincerely, Doopy :p
