Story-telling. Yeah, I know it's a bit self-centred. A lot self-centred. But I love story-telling. I could tell you a story about that ... but I'll refrain.
Second, since I gave up full-time teaching and went farming, is the money. When the farm co-operative is losing money or the rain isn't falling, and the payout for my production is falling, then the regular trickle of money from relief teaching is extremely appreciated. And, under lockdown, the government decided to pay me (and others like me - part-time on-call teachers) based on my average pay for the start of the year. So for 8 weeks I've been paid for teaching absolutely nothing!
Hmmmh. Getting students excited about stuff.
