You can only meet people from another household outdoors and in indoor public spaces for certain reasons, such as for work, to join your extended household, for sport, exercise, or to provide care and support for a vulnerable person. This can include providing emotional support for someone whose wellbeing is at risk, including for those who are isolated because of disability or a caring situation.

A maximum of 2 people, aged 12 and over, can meet outdoors for a permitted purpose, if they are not from the same household.
Children under 12 do not count towards households or numbers when meeting outside.
Children under 12 do not need to maintain physical distance from others indoors or outdoors.
The members of an individual or extended household can meet outdoors for sport, exercise or social interaction.
Those at a higher risk of severe illness from coronavirus (including those who had been shielding, people 70 and over, people who are pregnant and people with an underlying medical condition) should strictly follow the physical distancing guidance.
It is against the law to consume alcohol in any outdoors public place in any Level 4 area.
Marches, parades and static demonstrations are not allowed at this time.
Copy and pasted from Scotgov, I read that to mean you can meet someone outdoors inc the garden for emotional support.
