Here, the mother tells her son to come with her, but he refuses. He says 'Tegi maayo'. This means I'm not going. This piece of grammar is called the 'negative progressive'.

Tegi maayo - I'm not going
Tegi maysid - You're not going
Tegi maayo - He's not going
Tegi mayso - She's not going
Tegi mayno - We're not going
Tegi maysaan - You're(pl) not going
Tegi maayaan - They're not going

For any conj.1 verb,

base/imperative form + i + maayo
cun + i + maayo = cuni maayo - I'm not eating

Sometimes, you have to change the pronunciation,

Gal + i + maayo = Geli maayo - I'm not going in

For conj. 2 & 3 verbs,

kari + an + maayo = karan maayo - I'm not cooking

dhegeyso + an + maayo = dhegeysan maayo - I'm not listening

There are some special cases as well,

noqo (to return) = noqon maayo - I'm not coming back
