Case 1
When for example we say "At weekends I play football" what do we mean?
1). I always play football at weekends.
2). Some weekends I play football.
How "strong" is always in the first case? If we interpret it as "always" in the strict sense then it must be true in every time, that is from the day the speaker was born until the day he will die.
Case 2 What about sentences like this:
"I like playing football". Does the speaker imply that there is no case that he doesn't like playing football?
