Are your friends gritting their teeth today?

Spare a thought for the mothers of teenagers going through a rough time. Mother's Day might be a trial - and they may not be able to tell you why.

When I talk to parents, it's clear that raising a teenager can be one of the loneliest experiences of adult life. There are things you can't post about, can't always tell your closest friends.

If you know a friend whose teenager is struggling, a small gesture goes a long way. A text. A coffee. No advice - just being there.
