I started at South Primary in Paisley in 1987. The school was nicknamed Legoland. It was really colourful - yellow and blue at the front, with a red roof. It was also very bright inside and still had that new smell about it.
I can vividly remember the first day. There were loads of other kids outside the class crying their eyes out, not wanting to leave their parents, but I just wandered in, quite happy to go into the classroom.
I was one of those people who always tried to behave really well, but if there was anyone who was a bit disruptive I always joined in. I was never caught being naughty though. I was a bit of a teacher's pet, or at least tried to be. I was always a bit of a swot and wanted to be the first to answer everything.
My favourite teacher was Mrs McKellar, my Primary 1 teacher. I became really close to her. She was a really friendly person. She was a very young teacher, and she reminded me of my mum, although I don't know what it was about her.
I remember giving her hugs and her lifting me up once and asking me what fabric conditioner my mum used, because she thought that my clothes smelled really nice. She was a really encouraging teacher, and from what I can remember of the lessons, she made them fun.
I can actually remember once telling Mrs McKellar that I loved her, and also that I thought she had a lovely jumper on. Some things never change, because when I was in sixth year at high school, I really liked the English teacher I had, who was called Mrs Hoskins. She was wearing a tartan skirt and a tartan jacket, and I told her it was a lovely outfit. The class didn't really agree. But people who watch me on telly will know I like tartan - I wear quite a lot of tartan ties.
There was a real closeness and a bond with Mrs McKellar. Over the years, my grandad used to bump into her walking into town, and she would always be really interested to hear how the family was and how I was doing.
My grandad was such a gossip, he would tell everybody everything, so she was always kept informed about what I was doing and the fact that I wanted to become a weatherman.
I had been given a BBC weather- presenting kit for my seventh birthday. It was just a box with some weather instruments and maps with stick-on symbols. I used to stand up in front of my grandparents and my mum with this map and stick-on symbols and be like, "watch me do the weather".
Mrs McKellar wrote me a really nice letter when I first started at STV in 2007. Unfortunately, my grandad had passed away shortly before I started, so he never saw that, but he was the one who encouraged me. He had a real interest, and we had built a Stevenson screen together, which housed all our weather instruments.
So Mrs McKellar wrote a really nice letter, saying it's unfortunate your grandad hasn't seen you, but your grandma and your mum must be really proud of you. It was so nice that a P1 teacher, 20 years on, would still remember me and write to me.
The school has closed now, and my grandma was telling me she had spoken to Mrs McKellar and she didn't want to carry on with teaching because she had such a connection with the school. I think she now works in a florist's in Paisley. I would like to say thanks for everything she did in P1, for remembering me and for supporting me.
