When and how you two hug:

At first you loved his hugs but he always gets too excited which will cause his hair to burn and your shirt to catch on fire. Luckily he's always fast to do it out before you get bad burns. So now hugs barely happen which upsets him but he understands your reason.

When you wear a piece of his clothing:

Of course his jacket! It's cool with the flame designs. Whenever you wear it, Heath will grin and begin yelling pick up lines and comments at you. At first it's fun but then it gets too much so just throw the jacket back at him which will make him laugh.

When he sits on your lap:

He will do it just to annoy you. He will not calmly sit down either, he will just flop himself down on your lap which always makes you yell at him which he will just laugh off.

When your sick:

When you're sick, those are one of the times when you see Heath not joking around and actually being serious about something for once. He will buy you the right medicine and feed you. You will just laugh it off, saying you can still eat. But he will insist he wants to feed you.
